Gps Navigation For Your Car

Writen by Terry Brown

The GPS, which means Global Positioning System, is a fully-functional satellite navigation system. It has the capacity to provide people information regarding locations any time and any where on Earth. This type of technology has been greatly used and now vehicles could be installed with such systems. It could assist drivers on knowing the right roads to tread on as well as giving drivers information on the roads to their destinations.

If you are interested in having a GPS navigation system for your car, you would to do some thinking first. There are in fact a lot of things to consider and to check before you go ahead and purchase that navigation system. One of the very first things would be to think and choose as per how often you would be using the system. Just like any other feature of a vehicle, the GPS navigation system comes in a variety of prices and specifications. Of course, there are inexpensive ones but are not user-friendly.

It would be also very helpful if you try to check out your car's layout also. You see, there are some GPS navigation systems that come with a monitor which shows you a map and this monitor is usually installed on a car's dashboard. Try to see if your vehicle could support such. You would not want to have a crowded vehicle just to have a GPS navigation system.

A system that has the capacity to find out multiple ways to get to your destination should be one of your choices. That way, you would be getting the most out of your vehicle. Also, try looking for a system that provides directions. There are some that gives you arrows that show you when you need to turn during your drive. Another important specification that you should consider when choosing a GPS navigation system is that it should also be capable of updating its data and information.

Things are constantly changing and with GPS systems that could be updated, it would show you that your system could be put to use for a long time. On the same line, Auto Parts Information also is continuously updating its collection of Mercedes Benz partsand other auto parts for its customers worldwide.

Xm Radio Installation For Auto Shops

Writen by Lance Winslow

As many companies try to diversify their trade services we are seeing a rather unusual migration to services that one might never think possible in the Oil Change Quick Lube Industry. One company we visited had closed one of it's bays since it had a Wal-Mart across the street and started to install car stereos, specifically XM Radio. Now we tested the XM Radio ourselves and our gut feeling right away was this: XM Sattelite Radio is great.

I recommend everyone buy a system for their car of Satellite radio. Go to

http://www.xmradio.com

and check it out. It is very excellent, inexpensive and impressive, soon it will be offered for your wireless PDA. Sirius is also good and has 100 channels their website is

http://www.siriusradio.com

It appears that the radio station industry may be the next hit with advertising lost revenue as more and more people go to satellite radio and dump their regular radios. This is going to hurt them because new car buyers are getting the XM and Sirius systems and many are buying gift certificates for loved ones at Best Buy and Circuit City for after Christmas Installations. We know that the trade Journal Industry is tanked and consolidating fast, that Advertising magazines is way down. That companies like Procter and Gamble and Unilever paying for advertising on results only. Advertising firms are going the way side and this is hurting the industry badly and causing empty office spaces in downtown sections of large cities. Satellite TV has also hurt TV stations by adding channels and therefore people flip channels more often some stations disallow flipping on certain commercials for an extra fee.

Now after reviewing this we have determined a few more facts and after our discussions and confirmations with this Quick Lube we found they had actually increased sales in their two bays to equal the three bay max volume. Simply by installing stereos and developing another set of new clientele, younger crowd on average and there seems to be no end in sight to the number of new people wanting these systems. Just a thought if your volume of oil change customers base is dwindling due to a local low priced competitor, that you might think of other revenue streams to make the lease payments.

Gps Systems And How They Work

Writen by Michael Russell

GPS stands for global positioning system, a system that has been established and is managed by the Department of Defense. The GPS system utilizes satellites that have been put into orbit that help people determine their exact positioning on the plane t- whether it be for the purposes of navigation, for the purposes of military use, or any type of enterprise that requires an exact global positioning by latitude, longitude and altitude. In fact, sometimes GPS systems are installed in vehicles, and some are installed in fishing boats. Finally, some GPS systems are fixed into position, while some are portable.

GPS systems can also be purchased for motorcycles, and hikers sometimes use such systems to determine where they are while walking. Cyclists should not be left out of the mix, and runners, joggers, and skiers use navigation systems to prevent themselves from becoming lost in an unfamiliar area. Some PDAs - personal digital assistants - are equipped with built in navigation devices, while some Palm devices also include such systems.

Navigation systems are sold with a variety of features and what kind of features you should look for is solely dependent on two factors - price and need. The most basic of navigation systems will provide you with a route from one waypoint to another waypoint or to multiple waypoints, depending on your destination and trip plan. A benefit of such navigation systems is that they not only serve as a guide to your preplanned destination, they also serve as guide back to where you started. Any route you plan in a navigation system is completely reversible thanks to the innovative design of such systems.

Alternatively, you may pay more money for a navigation system that has voice capabilities. You can purchase a navigation system that will guide you to your destination vocally and while speaking to you it will offer up a turn-by-turn dictation of your journey. Conversely, those individuals that spend the majority of their time travelling - like a delivery man may find that they prefer a navigation system that they can preplan many destinations at one time and then move from one set of directions to another. Thus, such individuals require a uniquely designed navigation system -one that possesses multi destination capabilities. Finally, there are different navigation systems for boats, motorcycles, cars, and joggers so you will need to be sure to purchase the product you require for the use for which you intend it.

Navigation systems can be easily ordered from online distributors. If you are interested in purchasing a navigation system you may want to read the myriad reviews offered pertaining to such products before you make your purchase. In doing so, you will have a better idea of the various brands available and what other people recommend. Also, you will find complete reviews that will allow you to engage in comparative shopping - this way you know you will be able to find the best navigation system to meet your needs at a price that suits your budget.

How Do Xm And Sirius Satellite Radio Compare

Writen by Jim Johnson

If you want to take advantage of the satellite radio boom which is picking up steam with almost every passing day, you only have two major choices if you live in the US, either XM or Sirius. Both providers offer high quality, digital programming with over 100 channels to listen to so you can never run out of something good on the radio.

But what are the differences between the two services? It makes sense to figure that out in advance and make the right decision for you, as the equipment that you buy that enables you to receive the signal from one of the providers, cannot be used with the other provider if you decide that you want to make a change for some reason. So that means that examining the programming options from both XM and Sirius is an important step in the buying process, as it will be very expensive if you decide to change after the equipment has been purchased.

In actuality though, there are more similarities between the two providers than there are differences, especially in the field of music. Each has over 60 channels of music to tune into including all of the major generes like pop, hip-hop, blues, all kinds of rock, country, jazz, classical, as well as dance music and music by the decades (70s, 80s, 90s, etc.) So in this area, either one will no doubt provide you with all the music programming that you could ever need.

The differences in programming start to show up in the talk radio and sports radio sections though. In sports, XM broadcasts baseball games and Nascar, whereas Sirius has committed to more overall sports programming including all NFL footbal games, most NBA games, NHL, and Nascar. So if you are a sports fan, the differences can be important in this area.

In talk radio, one of the biggest draws for Sirius is Howard Stern. Of course, his radio show has been very popular for many years and has lots of listeners, so if he is a favorite of yours, you can only find him on Sirius. But there are other talk shows available as well, although Sirius tends to attract more celebrity talk shows hosted by the likes of Martha Stewart, Jimmy Buffet, and more. One other advantage in the talk area, is that Sirius also carries NPR, which has a wide fan base as well. The list is constantly changing though, so check the latest channel lineup to see what talk channels are being offered at this point.

Both services offer always-on, everywhere service that is available no matter where you live in the US, and the equipment for receiving each service is pretty extensive, with XM maybe having a slight edge in the portability field.

So look over the channel lineups carefully, choose your provider and enjoy the next step in high quality, digital entertainment.

Gps Basics Part 1

Writen by Zvi Braverman

This article is the first of series of three articles in which I'll explain some basic principles and concepts of GPS. I in this article I'll explain how exactly GPS works so it won't be a mystery anymore. I'll also mention some recent enhancements to the GPS system. In the second article I'll explain about some of the GPS core technologies, so when you hear the magic words "Sirf III" you'll know what people are talking about. And finally, in the third paragraph I'll make a short review of the leading GPS manufacturers on the market today.

First of all GPS stands for Global Positioning System and usually refers to the GPS receiver. The receiver basically receives the signals incoming from constellation of 27 satellites which are orbiting the Earth (actually there are only 24 satellites that are operational and 3 additional for backup in case one of the 24 fails) and from those signals can calculate it's absolute position on Earth. This satellite system was developed by the U.S. military and after a while U.S. government opened it up for public. Those satellites are circling the Earth making two complete rotations every day. Their orbits are planned the way that at any time and anywhere on Earth there are at least four satellites "visible" in the sky. A GPS receiver locates four or more satellites from the signals those satellites send constantly towards the Earth, calculates the distance to each of the satellites and from this information calculates its' absolute location on Earth. This process of pinpointing the location of the GPS receiver is based on mathematical principle called trilateration.

Let me explain a little about this principle regarding the GPS. It is a little tricky so if you don't want to bother yourself with details – just skip this chapter. Like I said, GPS receiver locates the satellites and calculates the distance to them. Lets say for example receiver knows that Satellite_1 is located 20 miles from it. In the whole space Satellite_1 can be anywhere on a huge Sphere with radius of 20 miles around the receiver. If receiver also knows that Satellite_2 is located 30 miles from it, it can overlap the sphere of satellite_1 with the sphere of satellite_2. The spheres intersect in a perfect circle (think in 3 dimensions). The distance to the third satellites gives us a third sphere which intersects with the circle in two points. One of those points is located in space and the other located on Earth. This second point is actually the location of the GPS receiver. Using the Earth as fourth sphere, receiver is able to choose that second point and this way it knows its' exact location on earth.

Basically GPS receiver needs to locate only three satellites but it always tries to locate as many satellites as possible because it improves the accuracy of the result.

The signals that satellites are constantly transmitting are high-frequency, low power radio waves which contain information about the satellite and its' location. GPS receiver can calculate the distance to the satellite by counting the time it takes to the signal to get from the satellite to the receiver.

The whole process described above works well but it has inaccuracies due to several reasons like signal interference,weather and more. Differential GPS (DGPS) helps correct those inaccuracies. This enhancement is base on stations located on Earth. The hardware at those stations knows exactly the location of the station and constantly sends information to GPS receivers (but only to those in which this technology is implemented) how to correct their results so the will be more accurate.

Once the GPS receiver made the calculation, it can tell the latitude, the longitude and the altitude of its' current position. This doesn't tell much to the average user. So in order to make the use of the GPS receiver more user-friendly many receivers send this data to a program which displays a map and can show the position on it.

Well that's it for this article and check for updates, because like I said at the top of this article there are two more articles on the way!

Gps Buying Tips For Technophobes

Writen by Gary Ruplinger

Black glasses with masking tape holding them together and a pocket protector are no longer a required part of the uniform for GPS owners. GPS has gone mainstream. But if you're still not up to date on what it is and how it works, and if you'd like some advice on what to buy, this article will bring you up to speed.

A GPS device is like a map on steroids. First of all, it always gives you that little "You Are Here" dot – you no longer need to figure that out for yourself. And all you need to do is tell it where you want to go and it will plot the course for you. It doesn't end there, however. New GPS units will provide you with voice guided directions for the entire trip, tell you where the nearest gas station is, and will even put you back on course if you take a wrong turn.

GPS stands for Global Positioning System, a system of 28 satellites orbiting earth. It was originally developed for military use, but its uses have spread far beyond just military applications. Your GPS unit can receive signals from these satellites, and by using these signals, calculates your position (within 3-10 meters), direction, altitude, and velocity. Once your GPS unit knows where you are, it can help you get to where you're going as long as it has mapping software installed. All but the most basic GPS devices currently have mapping software.

Now that you know a little bit about what a GPS device is and how it works, it's time to educate yourself on the features available and decide which unit will best suit your needs. There is certainly no shortage of GPS devices available, so doing a little research can save you a lot of time and hassle.

Step 1 - Which type of GPS do you need?

There are four main types of GPS units; the car navigation system, the portable outdoors unit, the marine system, and the PDA/GPS hybrid.

If you're mainly planning on using your GPS to get you from point A to B in your car and don't think you'd use it for much else, your best bet is the in-car navigation system. These systems can be built in to your car or you can purchase a device that mounts onto your dashboard. Desirable features for the in-car systems are: voice guided directions; detailed built in maps; touch screens; rerouting in case you get off course; and a database with points of interest to help you find the nearest gas station, restaurant, and many more places along your route.

If you're going to want a GPS device that isn't limited to the car, then you may want to consider a handheld GPS (http://www.gpsmaestro.com/handheld). These devices are ideal for anyone who loves to hike or bike. Features to look for in a handheld unit are: lightweight, rugged, waterproofing, long battery life, color screens, and mapping features. The handheld GPS units are geared towards people who spend a significant amount of time outside. For example, if you're out hiking you can easily track where you've been; mark your own points of interest; and even find out how far you've gone and at what speed. Many new handheld devices offer some navigation features while driving. You can even purchase handheld units that offer built in radios that will not only allow you to communicate with other members of your party, but will also display everyone's location on your screen.

If being on the water and fishing is your thing then you should probably consider a marine GPS. These units are specifically designed to be on and around water. All of these units will feature waterproofing and should have screens that are easy to read even in bright sunlight. Some other good features to look for are: color chart plotters, onshore and offshore maps, fish hotspots, and sonar capability. You may also want to consider a unit that will function as your car navigator, eliminating the need for two devices.

The final category of GPS device is the PDA/GPS hybrid. This device offers a good combination of the car navigation systems and handheld devices. You'll get the large screen that you'd find in the car system and the portability of a handheld unit. Also, you get a PDA to help you keep organized. One drawback is the limited selection of these units. Only a few companies have attempted to make an integrated unit, and all have some serious limitations.

If you are considering a PDA/GPS hybrid, I'd recommend you purchase the PDA separately from the GPS. Find a PDA that offers all the features you want in your PDA, then look for a GPS receiver that will attach to your PDA via Bluetooth. The features to watch for are the same as listed for the in car systems. All of the current PDA/GPS devices are better suited towards driving than hiking, although they do offer the portability for outdoor activities if needed. This category probably offers the most potential of the four, but it is also the newest, so watch for significant improvements in this category in the future.

Step 2 - Budget Considerations

If you're on a budget, then it's important to decide which features are most important to you. If you want a full featured car navigation system, it can easily run over $1000 (and over $2000 if you want one that's built in). If, however, it would be more of a toy to play with, then a handheld device could be a better choice as they can be as low as $100 and are rarely more than $500. Marine GPS devices vary widely in prices, but a very good device can usually be purchased for no more than $1000. If the PDA/GPS devices interest you, they typically range from $400-$900.

Step 3 - Where to Buy

Finding the right store to purchase your GPS device can be difficult. Most stores only carry one or two kinds of GPS. For example, if you go to a sporting goods store you're likely to find the handheld GPS units and marine GPS units but not the car navigation or the PDA/GPS hybrids. I actually prefer shopping online for GPS units as the prices will likely be lower, and you'll be able to read user reviews of the items before you buy. Just make sure that if you have a problem with your GPS you are able to return it.

Owning a GPS can be extremely helpful, especially if you tend to get lost a lot or if your glove compartment is overflowing with outdated maps. They can also make planning a long trip to an unfamiliar area a breeze. Deciding which GPS to purchase can be difficult, but as long as you make a list of the features you absolutely must have then all you have to do is find the units that match your budget. Read reviews from other owners and you should have no trouble at all. Once you purchase your own GPS unit, you'll wonder how you ever lived without one.

Cell Phone Gps Tracking

Writen by Alan Chestnutt

The development of communications technology has long since surpassed the sole ability to access others when they are mobile. Today, mobile communication devices are becoming much more technologically advanced and offer more than the ability to just carry on a conversation. Cell phone GPS tracking is one of those advances.

GPS or Global Positioning System tracks your location by interpreting the data received from 3 or more satellites. This has made GPS a popular feature in cars as a navigational aid.

All cell phones constantly broadcast a radio signal, even when not on a call. The cell phone companies have been able to estimate the location of a cell phone for many years using triangulation information from the towers receiving the signal. However, the introduction of GPS technology into cell phones has meant that cell phone GPS tracking now makes this information a lot more accurate.

With GPS technology now more commonplace in many new cell phones, this means that the location of anyone carrying a compatible cell phone can be accurately tracked at any time. Cell phone GPS tracking can therefore be a useful feature for business owners and fleet managers who need to be able to keep track of their vehicle movements.

Cell phone GPS tracking can also be a useful feature to the emergency services or police when responding to a 911 call from a GPS cell phone. For this reason, the FCC has legislated that wireless networks provide location information for 911 calls made from cell phones. These are known as E911 calls.

As technology advance even further, future features will be even more powerful. Imagine GPS cell phones used as a navigational device. Based on the cell phone GPS tracking signal, they could be used to find your way to a location, calculate your speed based on your location change over time, from this calculate your estimated arrival time, suggest an alternative route and even phone the person you are calling to see with your ETA! Of course in car GPS navigation systems can already perform many of these tasks, however it is the portability of cell phones that makes them so useful for this technology.

Cell phone GPS tracking could also be used to locate the whereabouts of your children and offer protection to elderly relatives should something happen and they need urgent assistance.

These features will help to secure the future of cell phone GPS tracking providing advantages for all.

Hd Radio Update Clear Channel And Entercom Begin Rollout Of Hd2 Channels

Writen by Douglas Hanna

One of the things that makes HD Radio so exciting is that it enables multicasting. This means a station can broadcast its normal programming, plus a second channel with an entirely different format. For example, KIOI-FM in San Francisco is broadcasting both Hot AC (Adult Contemporary) and 80s pop hits on an HD2 channel. Best of all, these HD2 channels will be commercial free -- at least for the time being.

Clear Channel has announced a roll-out schedule for adding HD2 channels in 28 of its markets, including New York City, San Francisco, Dallas-Ft. Worth, Chicago, Los Angeles, Philadelphia and Washington, DC.

Note: For a complete list of Clear Channel markets, stations and its new HD2 channels, you can go to the HD Radio Blog you will find on my web site listed below.

Entercom

A second broadcaster, Entercom which owns and operates more than 100 radio stations across the country has announced that it is also beginning to add HD2 channels. The first markets to see these stations will be Boston, Denver and Portland.

Both Clear Channel and Entercom will soon begin promoting HD Radio with contests, give-aways and on-air commercials. And Entercom has said it is also negotiating accelerated roll-out efforts with retailers such as CarToys and Ultimate Electronics.

HD Radio is also great in that it enables AM and FM radio stations to broadcast their programs digitally, a tremendous technological leap from today's familiar analog broadcasts. These digital broadcasts provide listeners with radically improved audio quality, more radio channels through multicasting, and new data services. In fact, with HD Radio, stations can actually send you helpful information such as traffic alerts and weather reports.

More than 15 manufacturers now offer HD Digital Radios. Online and in-store retailers selling HD Digital radios include: ABC Warehouse, Audio Adviser, Bjorn's, Boston Acoustics, Car Toys, Great Indoors (a unit of Sears Roebuck & Co.), Harvey's, eBay, J & R Music, Listen Up, Magnolia Audio Video, One Call, Ovation AV, Radiosophy, Tweeter and Ultimate Electronics.

Sirius Radio Everything You Ever Wanted To Know

Writen by Nick Smith

Sirius radio, or more generally satellite radio, came out just a few years ago. If you've never listened to satellite radio or heard about it, this article is your lucky break. In this article you'll find out what satellite radio is and how it works.

What Is Satellite Radio?

Just like the name indicates, satellite radio uses satellites and related equipment to broadcast radio channels to car or home radios. The concept really received its impetus in 1992 when the FCC set aside a chunk of radio frequency for what they called Digital Audio Radio Service (DARS). Five years later, Sirius Radio and XM Satellite Radio purchased licenses from the FCC, and both companies started putting the pieces into place to be able to start broadcasting.

Conventional radio waves can only travel 35 to 45 miles before they die out. The signal for satellite radio services is broadcast more than 20,000 miles above the Earth's surface. Programming on satellite radio is subscriber based, meaning you pay a monthly fee to descramble the signal from the satellites. But, most satellite radio service comes commercial free, so you don't have to worry about channel hopping. Channels include music, talk radio, sporting events, kids programs, and news.

The Who's Who of Satellite Radio

There are currently three major players in the satellite radio game: Sirius radio, XM satellite radio, and WorldSpace. Sirius radio covers North America, including the continental U.S., Canada, and Alaska. XM provides service in the continental U.S. WorldSpace is developing coverage in other parts of the world (Asia, Africa, Europe, and South America) and are definitely the most ambitious in terms of client coverage (a potential of 4.6 billion clients covered on 5 different continents). Each company uses different satellite technology and methods to provide service in their respective areas.

Satellite radio equipment, such as car receivers and home stereos, are sold at a variety of consumer electronic stores, and are starting to become standard installations in new cars. Conventional radios cannot receive satellite radio transmissions, so picking up the service usually entails purchasing a receiver, though some kits are available to make conventional radios satellite-radio compatible.

Because of the different technology each company utilizes, receivers are not compatible with every company. For example, if you subscribed to XM but then wanted to switch to Sirius radio, you would need to get a new receiver that was compatible with Sirius. Some satellite television companies include satellite radio service in their channel packages, and you can receive the transmission through your television satellite dish.

How Does Satellite Radio Work?

This is the cool part. The music, talk show, sporting event, etc., are recorded digitally in a studio, after which the message is encoded. The encoded signal is sent to the satellites from ground stations (Sirius radio based in New York; XM based out of D.C.). The satellites then relay the signal to receivers in your car or at home. The receivers contain chipsets that decode the signal and play it through you stereo. In urban areas where taller buildings might block the signal from the satellites, ground repeaters or transmitters are used to resend the signal, eliminating pockets of dead space.

XM uses two satellites to cover the continental United States with their signal. Sirius radio uses three satellites to form a satellite constellation. The way they are set in orbit ensures that each satellite spends about 16 hours at a time covering the U.S. and that there is always at least one satellite over the U.S. at any given time. WorldSpace satellites beam three signals each to increase the amount of territory they are able to cover with their three satellites. All three companies have reserve satellites ready to launch in case one of their satellites stops working.

Satellite radio technology looks like it's here to stay. It is ideal for those that live in areas where normal radio reception is poor, or for those willing to pay a little each month to not have to listen to commercials. Chances are good that soon every new car you buy will have satellite radio installed, and that more and more homes will be equipped for it. I have only covered the basics. It is definitely worth your time to find out more about what each company has to offer.

Gps Navigation A Necessity For All Drivers

Writen by Justin Brown

For any driver travelling some distance, GPS navigation systems are essential and can save both time and money. Many people will think "I don't need one of them, I never get lost", nevertheless at the price that you or I could pick one of these up for these days, it's common sense to purchase one for even the occasional drive to a new location.

The GPS systems that are available today offer a lot more than just the map info that many people assume. Since GPS systems have arrived, the technological advancements have added such benefits as locating hotels and restaurants, and notifying the driver of speed cameras nearby. Furthermore, they constantly update with a detailed map of the area, with details of nearby facilities like hospitals; which is a feature that can be highly advantageous in an emergency situation.

The majority of vehicle manufacturers are capable of providing the car buyer with a built-in GPS system. These systems are able to advise the necessary authority of the vehicle location in scenarios where the vehicles' airbag is deployed, and also when the car has been reported by the owner as stolen.

The detail that many GPS systems can provide in terms of road maps and directions is incredible. Even when abroad, the relevant software is available for you to be able to use your GPS there. The software is regularly available via the internet for the GPS user to download instantly, and to benefit from in almost, if not all countries.

So let's take a look at some of the most useful and "must-have" options with a GPS device:
- A good viewing screen is vital as it obviously displays all of the data that you will need to see. Make sure it will be clearly visible and easy to understand whilst driving, and all information is displayed in a simple easy-to-follow manner.
- Consider selecting a GPS product that is easy to use, so that you do not need to fiddle around with the setup whilst in the car, but instead can set up what you need in a few seconds.
- Purchase a device that has good mapping software, which will display detailed streets and information on facilities. Ensure that it can also be updated online so all information can remain current.
- A voice enabled system is highly important, as it allows the driver to find their destination without taking their eyes off the road to constantly check their position on the GPS.

For those that do not have a GPS device, you may still decline the need for such a product; however for those that own one, i'm certain that they will never again be without one. They are practical to keep in your vehicle and provide good-quality information when required. They can save you time when travelling to a location and vehicle costs such as petrol whilst doing so. Take a look around at the GPS devices available to find out more detailed information, and to browse the deals that can be found. With the range of equipment available, finding one to meet your requirements should be relatively effortless.

The Fm Modulator Used For Its Convenience Not Quality

Writen by Jonathan Dalton

The FM modulator or FM transmitter is a device used to play your plug-and-play Satellite radio receiver through your vehicle's FM stereo. FM transmitters can also be used to play other digital audio devices like iPods, CD and MD players.

Normally second choice to an audio cassette adaptor because of sound quality, the FM modulator is still a very quick and simple way to get your plug-and-play Satellite radio receiver working in your vehicle.

Although sometimes only used if all else fails, the FM modulator at least provides an option for listeners who not audiophiles, want an easy way to hook up their receiver, or simply do not have a built-in cassette player in their vehicle.

Enough degrading these devices; there are probably thousands of Satellite radio listeners out there who will tell you that they experience good reception using an FM modulator. However, there is no doubt about it, an FM modulator, if used, can and will on occasions degrade the quality of audio output from your plug-and-play Satellite radio receiver.

An FM modulator converts the audio signal from the plug-and-play receiver into an FM signal, which is then transmitted over an unused FM frequency or station selected by the listener. The limitations of the FM frequency band mean this in no way represents what the signal actually sounds like.

There are two types of modulator available; wireless and hardwired.

The wireless modulator is built-in to a power adaptor that plugs into the cigarette lighter socket, the docking station or cradle that houses the plug-and-play receiver, or, more recently, the plug-and-play receiver itself. The receiver's audio output is transmitted over the air to an unused FM frequency.

The wireless modulator is convenient, easy to install and configure, but broadcasts only a very short-range signal prone to fading and with interference; comparatively weaker compared to a hardwired modulator.

The hardwired modulator is placed in between the vehicle's stereo unit and antenna. The modulator connects directly into the stereo's FM antenna socket to provide a better frequency response and a signal with less interference that is less lightly to fade.

It is recommended that a hardwired modulator be installed professionally, as it requires a connection to the antenna socket on the rear of the vehicle's stereo and to the electrical system, all located behind the dashboard.

The amount of interference, static and fading you experience, using either of these devices, depends on where you are geographically located in the US, quality of the in-built tuner or broadcast and the type of modulator installed in your vehicle.

For example, somebody living in a major metropolitan area, using a wireless modulator, will no doubt experience poor reception along with the frequent and often debilitating interference from other radio stations.

With regard to sound quality, the wireless modulator rests at the bottom of the pile with the hardwired version above it. However, depending on circumstances, hardwired modulators can be as good as cassette adaptors if not better.

Free Gps Software

Writen by Anne King

I took a look at some of the online offers for free GPS software and found, like many "free" offers there were often limits and provisos involved. Often the freeware is a scaled--down version of purchasable products. Sometimes the free product has restricted functionality with features disabled, other products are trial--based and are disabled after a certain time (hours or days or use).

An example of limited free GPS software can be found at GPS Utility. The downloadable freeware is limited 100 waypoints and 500 track points. (There are 65,000 of each in the registered version of their program.) The free program gives you a good opportunity to try before you buy, and this is the benefit of most free programs.

There are online sites that list various free GPS software and describe how to use the programs after you download them. Often individuals who have used the programs themselves develop the sites. These are great because they give you an unbiased interpretation of the benefits and disadvantages of the programs before you use them.

Using free GPS software you can download programs that allow you to retrieve and display aerial photos, topographical maps, USGS landmarks. There are programs available that allow you import scanned images and add latitude and longitude points and other data.

Free GPS software downloads are available for PDA units that are capable of communication with GPS receivers. With these downloads you can have a useful navigation assistant, location database manager, and GPS data converter.

Programs to manage GPS waypoint and route files are available for both PC and Mac users. The waypoints and route files can be saved or converted to various formats used by other mapping programs.

If you need to transfer information to and from your GPS receiver and your home computer or laptop there are several free programs that allow you to do so. There are also programs that allow Garmin GPS receivers to "talk" to one another.

Many of the programs listed here are directed at the hiking/trekker community, but there are also free programs available for auto GPS systems and marine navigational systems. I found a couple of marine navigation programs that allow you to download nautical charts and plotters.

There are free GPS software programs that allow you to download street maps that might not be included in your auto--navigation system. If you intend downloading in--vehicle software, make sure that it has audio capacity, an essential safety factor for motorists. One such program offers data for several countries with voice guidance in twelve languages.

Free GPS software is also available for downloading to your cell phone. This is mostly tracking software and can be phone specific. You might want to check with your carrier before downloading anything to your cell phone to make sure that it does not incur extra charges.

As satellites are constantly moving, it is helpful to know the optimal time for data collection in your area. There is free GPS software that includes an almanac to let you know the availability of satellites at any given time.

Some of the free GPS software is brand specific. Programs designed for a Garmin receiver may not work for a Magellan, so check out the specifications carefully, especially if you intend purchasing a registered version after your trial period. Other software works with most brands.

Is That Your Radio Sending You A Text Message

Writen by Douglas Hanna

HD Radio technology is the new, hot thing in sound. That's because it will do for radio what HDTV has done for TV – make it light years better. In fact, when you listen to HD AM radio, you'll think you're listening to FM. And HD FM radio sounds as clear and pure as if you were listening to a CD. Plus all this sound comes via the airways and i completely free!

Is that your radio displaying a text message?

Thanks to HD Radio technology, radio stations will able to also transmit additional information in the form of text messages.

Typically, this will appear as scrolling text on your radio's display. This information might consist of the song's artist and title, the station's call letters and maybe advertising information.

Yes, the additional information sent to your digital radio will most likely include ads. After all, advertising pays for those free radio AM and FM broadcasts.

These ads might consist of messages such as "this traffic report brought to you by Arnie's Automotive." Besides, all TV stations and even satellite radio have ads.

On the plus side, the text broadcast with a news show might be financial updates, stock ticker information or business news. And stations might also use text to provide helpful information such as weather updates and traffic alerts.

Just imagine. There you are in your car listening to an oldies favorite and suddenly, your radio tells you to expect bad weather in the next few hours. Is that amazing or what?

Go to http://www.hd-radio-home.com for more information on HD Radio technology, a partial list of stations already broadcasting in HD Radio technology, and information on HD car radios, receivers and portable radios.

How Gps Works

Writen by Anne King

Global Positioning System (GPS) is a navigational aid originally developed for the military. The system simply receives signals. It is the applied technology that gives the GPS its versatility.

If you have ever used map and compass, you will understand a little about how the GPS works. In order to find your position on a map, you need to have three points of reference. The intersecting line from the reference points is where you are. Map and compass work uses triangulation (bearings), GPS uses trilateration (distances) to calculate location. Satellites orbiting the earth emit unique signals that can be received by a GPS. The GPS software interprets the signal, identifying the satellite that it came from, where it was located, and the time that it took for the signal to reach the system. Once the receiver has both time and distance it begins to determine position.

Three satellites provide the intersection point and the fourth is used to check that the positioning is accurate. Accuracy depends upon the synchronization of atomic clocks in the satellites with the clock in the GPS system. Although the clock in the GPS is not atomic, utilizing the fourth satellite gives it that functionality as the internal clock adjusts itself to correct any discrepancy discovered.

GPS has gone far beyond its initial military application. Drivers can find their way through city streets, long distance trekkers use the technology to cross unfamiliar terrain, mariners and pilots use GPS enhanced data to cross the seas and skies.

In--vehicle GPS can be integrated into the car entertainment system or can be installed as a removable device. These systems need to tell the driver where he/she is and how to reach their destination. The information includes road directions plus relevant features along the way such as rest stops, gas stations, points of interest, etc. Auto GPS uses voice commands so that the driver can concentrate on the road.

Hikers and trekkers use similar technology, but normally without the inclusion of road systems on their devices. Mapping software defines the territory that the hiker will encounter. The user can enter waypoints (points of reference) so they can return using the same route. They can add points of interest such as water sources, possible campsites, and other items of interest on their trail. However, the portability demanded by hikers will also limit the functionality of the system as small screens mean that some detail will be lost.

It is GPS technology that is used to track individuals on home arrest, to trace missing pets, stolen vehicles, and missing people. Small systems can be incorporated into pet collars and wristwatches. As long as the receiver is active, it can be found.

Marine and aviation GPS units are sophisticated and specialized. The principles involved are the same as any standard system; the software is much more highly developed.

Any fisherman, who is using a fish finder on his boat, is using a GPS that is enhanced by sonar and tracking devices. Units have been developed for use on float tubes also -– as GPS technology advances, the systems become more and more compact and their uses more and more extensive.

If you are considering purchasing a GPS, make sure that it can be updated easily. This is especially true if you buy a multi--function GPS or one that is used where conditions change regularly. An in--vehicle GPS soon loses its usefulness if it is not updated as road systems change.

Updates vary according to the device being used. They can come in CD/DVD packages or as computer downloads. The user can purchase maps specific to the area in which the GPS will be used or a range of maps and routes. These are available from GPS software companies who will charge proportionally to the sophistication of the software.

GPS units vary in price according to their usefulness. It is possible to buy units for less than one hundred dollars to units costing more than one thousand dollars. What your needs are will be a factor in the cost of your unit. If you are a backpacker then portability is a major consideration. If you are a trucker, you need to be able to find a delivery point as quickly and conveniently as possible. Whatever device you go for, cost is generally related to quality. Buy the best you can afford.

Satellite Radio In Your New Vehicle

Writen by Jonathan Dalton

With Sirius and XM continuing to land partnership deals with just about every vehicle maker on the planet, the option to add Satellite radio in your new vehicle is being offered at more and more automobile dealerships across the U.S.

Though still not a common "standard" feature, the appearance of satellite radio as an available "option" has more than tripled over the past three years.

Factory-installed and dealer-installed options: Both Satellite radio companies encourage automobile manufacturers to 'factory fit' Satellite radio systems, this increases the chance that auto buyers will become subscribers.

New vehicles boasting a Satellite radio option come off a manufacturer's assembly line with either a partly or fully equipped Satellite radio system. In most cases, a new vehicle will arrive at a dealership with a factory-fitted in-dash "Satellite Ready" radio. The dealer will then quote a price to supply and install the remaining equipment necessary, usually the Satellite tuner and antenna.

Without doubt the option of factory or dealer-installed Satellite radio in your vehicle has its benefits; a clean installation with no visible hardware, plus the best sound quality available being the most obvious. The price quoted at dealerships varies depending on the type of equipment, but expect to pay between $300 to $800. The good news is that you don't have to go with a dealer-installed tuner and antenna; you can purchase aftermarket gear and install it yourself for great results and big savings.

Subscription costs: Although there are many vehicles now available with Satellite radio as a manufacturer-supported option, this typically does not include the cost of the subscription to the service, only the cost of the equipment. However, the majority of automobile manufacturers and dealerships are offering incentives, normally a three-month trial subscription to the service with no activation fee.

Can I choose which Satellite radio service? Unfortunately, exclusive deals made between automobile manufacturers and Satellite radio service providers, mean that few dealerships are able to offer a choice of Satellite radio services (see chart below).

Which vehicles offer a Satellite radio option? The chart below shows which Satellite radio services each automobile manufacturer is offering. It's worth remembering that not all the models in a manufacturer's vehicle range offer Satellite radio as an option.

Before long I think we will see Satellite radio become a standard feature in all new vehicles across the nation, with a buyer only having to decide on a payment plan and activation fee. Furthermore, buyers will have the choice of either service.

What Are Gps Cell Phones

Writen by Rhon Dafin

Fads come and go. But when it comes to technology, every trend is a worthwhile experience.

Take the case of mobile phones. From the plain call and text features, the cell phone industry has definitely gone a long way.

Today, cell phones are made more innovative by applying technologically advanced applications such as GPS or Global Positioning System. Equipped with this remarkable device, cell phones can now operate beyond their basic functions.

With the GPS system, cell phones can be used as a tracking device that enables people find the right places or even hunt down a relative or friend on his exact location.

GPS or Global Positioning System is a device used to pin down people's specific location anywhere on earth. The central hub of the system depends on "24 satellites" that move around the earth two times a day.

The identification of certain locations was made possible using fully operational devices that includes a series of receivers and satellites.

The information gathered by the satellites are being transformed back to the earth using exact timing indicators to receivers such as GPS cell phones. In this way, the hunted person's exact location is identified based on altitude, latitude, and longitude measurements.

Back then, the magnitude of GPS were only utilized in navigational purposes as well as for "land surveying," and map-making. But since the proliferation of the new technology, the utilization of GPS has significantly increased.

Today, GPS-enabled cell phones are being used beyond their usual features. With the help of GPS, people can now locate new addresses and navigate a new place without the difficulty of turning to your maps every now and then.

With GPS, cell phones can demonstrate the exact areas where to turn right or left. Hence, the need for a true GPS tracking device is lessened as more and more cell phone companies are gradually employing the utilization of GPS.

In fact, it was the Federal Communications Commission (FCC), which had instructed various cell phone companies to equip their new mobile phone models with GPS "tracking mechanisms." The agency said that with GPS-enabled cell phones, the user's location could easily be tracked within 300 feet anyplace on earth.

This proposal of the FCC had been based on cases where people are using their cell phones to call 911 during emergencies. FCC further explained that the utilization of GPS cell phones would expedite responses to any one who will need such assistance.

However, the initial reactions of most cell phone companies is slightly on the negative side. They believe that using "GPS chips" will only add to the cost of each product. Today, cell phones are literally being given away free when purchased on regular mobile service plans.

Nevertheless, the probability of earning additional incomes were seen by other cell phone companies. They know how information-hungry people are nowadays ever since the Internet technology had dominated the communications industry.

Even if it means egotistical commercial gains, most cell phone companies believe that the utilization of GPS cell phones are important in today's modern world.

One of the probable profits that the commercial market can gain is the distribution of graphical advertisements on mobile phones with the help of GPS. Hence, it is not surprising if one day, your cell phones will turn into small posters or advertisements notifying you of the latest event in town.

Indeed, with the introduction of GPS cell phone in the market today, people will have to change their units again just to cope up with the ever-changing world of the communication industry.

From 3G or the third generation technology to GPS, cell phones have definitely gone a long way since it was created for a simple call. With these features in your phones, what more can you ask for?

Gps Navigation Systems And Data Problems

Writen by Lance Winslow

We have a serious problem brewing with GPS navigation systems for automobiles and even motorcycles. There are however problems with this devise as a high tech toy are more serious than you might think. Ask anyone in a metro area who has bought a new car with one of those cool GPS upgrades for their SUV or new sports car. We have had our customers complain (customers of the carwash business, which is my profession). Oh they love the gadget, but they are under whelmed by the lack of data and streets, which are not listed. You see we have been seeing incredible suburban growth in many cities. Places near large DMA metros are a problem out in the middle class suburbs. In many areas such as outside Chicago, Los Angeles, San Diego, Phoenix, Las Vegas, Seattle, Portland, Denver, Dallas, Houston, Austin, San Antonio, Nashville, Kansas City, Minneapolis, Columbus, Cleveland, Baltimore, Jacksonville, Tampa Bay, Miami, Orlando, Atlanta, DC Subs, etc. And in NJ, NC, NV, OH lots of other fast growing growth pockets.

When GPS devises for cars first hit the scenes at the CES and SEMA shows in 1996, they became increasingly more popular, powerful and better data. But like VHS and Beta, Apple and IBM, competition became increasingly greater causing much consolidation in the industry along with patent fights. Much of the technology was former Defense Contractors peddling their wares through subsidiary consumer level companies. But the tight market remained due to the costs. Meanwhile companies like DeLorme and others tried to flood the market with low priced GPS units, which made things even more competitive. And the bugs were not fully out of the system yet. Someday all cars will drive themselves and people can watch TV, do video conferencing and use their transportation as a portable office or entertainment system while they are being driven to the location they have punched into their computer. Some things will have to occur before this is a reality of course. But eventually your dexterity skills to actually pilot a car will be worthless and un-needed.

First the satellites will need to be laser aligned and use multiple satellites to get absolute locations of ground items and vehicles. The cars will need to have additional anti collision devises made up of networked sonar and optic flow sensors. All of which are now available and the technology is getting better and better. Many military applications today will be civilian tomorrow. Just like Radar, Microwave ovens, Nuclear Energy, Cellular Phones, Satellite Communication and Jet Aircraft in Commercial Aviation. The flow of transportation will be brought to the next generation to serve man better.

For the time being the incremental changes in these technologies has hit a slight road block even though Honda, GM, Ford, Mercedes, Daimler Chrysler and Toyota have invested billions in anti-collision and safety devices which they will add comfort and desirable options which they can sell to customers as upgrades. Smart Car Technologies can add Thousands of Dollars to the price of a car and consumers are glad to pay for them. A factory GPS system with display can cost up to $6,000.00 and they sell a lot of them on the higher end cars. It is a high profit item upgrade, although there are some, which only cost $1000. And if you wish to compare these, some are very incredible with many features;

http://www.gpsnuts.com/myGPS/GPS/review%20...he%20review.htm .

There are many companies, which sell after market computer assist items. These companies are doing quite well and the systems work great. The big issue is just because you have a super duper incredible GPS system, does not mean the street you are looking for is even on the map yet. In other words it is like using an old map. If you are a studier of maps like I happen to be, you will see the problem with older maps. Even some companies keep printing old map data year after year without adding in new on ramps, city streets, infrastructure freeway improvements and ring-roads, it is aggravating for those from out of town. Even more aggravating looking for an address or street in a new housing tract, which you can see but the devise insists, does not exist? Then there are problems in areas like Cape Coral, FL and Tehachapi, CA or El Paso, TX and Knoxville, TN where the roads have been scraped and ready to put in or put in but do not connect or have nothing there yet. Of course it is very aggravating to see a road and try to go down it and find it is a dirt road that connects to nothing yet or an entire sub-division that does not exist? Is it a Mirage? If so where is the white Tiger Show?

Jack Dangermond of ESRI had set up entire networks of software makers who developed data for their awesome software products for GPS and GIS needs. Used by government, military, utility companies, transportation companies, private companies with GPS units to sell to the public, First Responders and school districts for buses. After the Dot Com crash those software companies were among some of the survivors, but had significantly cut costs. Thus without the proper data the GPS systems bought by the upper, upper-middle and middle class for their cars were not always good enough to support the price point for the newest technology. This is especially upsetting since the upper, upper-middle and middle class citizens who pay the most taxes live in the suburbs for the most part. The chances of a middle class American; who bought a home during the 3 years last housing boom; not being able to find their house or street on their new GPS devise is a higher probability then them actually finding it. We interviewed one man who bought a new Nissan Sports car.

Who lives in a newer developed area in the higher end Las Vegas, Clark County Suburbs, which only had the main streets on his GPS and had huge blank spots on his device? Some GPS devices allow the user to choose a satellite vendor and data vendor and software, but many of the Factory units do not. People think they are getting something really good and then find they cannot use it to navigate, which would really piss you off considering you may have paid as much as $6,000 for the unit. Even more dangerous is the information we learned from an EMT ambulance driver in Dallas area who told us of looking for streets for 15-20 minutes after battling through suburban gridlock to get to where they thought it might be. 3G cell phone technology may assist for those using cell phones to call in data to the dispatches. For all the training we are doing across this nation for first responders and on-going education of police, fire, Hazmat, etc. it appears that we have forgotten the problems of the system. Any time you build a system to serve humankind you must make it simple and make it work, that should be the first, the very first priority, then you can fix all the other issues.

With that said we interviewed a lady recently one evening who had a hell of a long day working for the Metro Police Departments Central Nervous System. The communications center and dispatch is to what we are referring. Although she was unaware of the problem at the center for bad data or missing data in the system, she could not say how they were able to get the information. Luckily serving a metro area they are probably connected to the planning departments computer, which they should be. And if the police department has the new data and no problem in this case, why have the software vendors not been able to access the data? It is a safety issue if someone with a GPS system pulls out a map and tries to read it while driving in an area they are not familiar with. It is guaranteed that in the history of the automobile in this country more people have been in serious traffic accidents from trying to read maps, than talking on cell phones, although cell phones no doubt a contributing factor in many lesser accidents will eventually pass this figure. Where the streets are, well frankly I cannot understand the need to keep this a secret unless it is the layout of Area 51, Prison, Power plant, Pentagon grounds, Military Bases, etc. If the emergency first responders divisions and contractors would share the data, there might be less accidents and they maybe able to get some assistance from the public being the eyes and ears

http://www.lancewinslow.org/nmwp.shtml

and also perhaps they could in fact use the idea of Smart Virtual Mobile Communities or FlashMob scenarios since budgets are strapped as the National Security "Red-Orange-Yellow-High-Risk-Danger-Days" come with high frequency, more police and first responders are on duty and that costs money. Without significant inflows the coverage of the Grid of a city is in jeopardy of slower response times. Fast response times are the easiest way to keep the peace, everyone, which gets away can cause problems another day and of course in case of International Terrorist Attacks.

It is essential to have the data for these devises and everyone is better served when communication flows. GPS units provide that and the data should be readily available and probably it is best to have the cities using the same formats as first responders and the same data can be used for utilities, consumers, military and even census data or academia studying urban sprawl and growth rates to have infrastructures ready during expansion. Things like water and energy, which has obviously been a major focus here.

There needs to be a nationwide coordinated effort to see that such data is filtered into the private sector, because as it stand the companies have been hammered in the industry and cannot perform the services to bring this stuff to market. Communication is important for government and citizen a like, increased efficiencies in business will save the government money and provide additional tax base and funds on the income of such businesses utilizing such data, as well as save money and time for all the government services discussed above. If we want a screaming economy we ought to be thinking how we can streamline and accelerate the flow of information to increase efficiencies and allow a small portion of the gain from the expanded pie to continue the growth. In other words, we make it easier for the Florist to deliver, the school buses to pick up more kids per hour and the soccer mom to take more kids to practice and still have time left to shop all of which serves man. The digital GIS divide is as important for our economy as the Digital Internet Divide. Kids in sports do less drugs, become more competitive, have higher work ethics and soccer moms can help keep the retail economy going. Every time you ease the flow, more things are possible. The exponential increase in American productivity is needed to offset the time lost in traffic and congestion. GIS-GPS systems can help in any emergency or simply driving around town getting things done to check off one's list for the day.

Rfid Is Radio Frequency Id The Wave Of The Future

Writen by Jamie Hall

Here's something you don't often hear – how are you dealing with 'rifid'? OR RFID. If you DO often hear it, then this article isn't for you, it's far too simplistic. However, if you have never heard of RFID before, read on. It might just change your life, or at least the way you organize it. Radio Frequency Identification or RFID is the use of radio waves to identify objects; in English, the ability to track items without coming into contact with them. This is accomplished by a microchip attached to an antenna called transponders or 'tags'. The chip transmits ID information to the receiver which converts it to a digital format which is then read by a computer.

RFID isn't new, its been with us in its current guise since the early 80s, and around since the 1920s – you know the tag that they stick on jackets in the clothes store to stop you stealing them… However, its just grown up; businesses can track products throughout the manufacturing process from start to finish. These items can be tracked while in trucks, on shelves, wherever.

The Benefits of RFID include:
1. The ability to eliminate time consuming bar-coding or other tracking processes. Instead, all data can be collected along the production line. This also helps to lower production costs.
2. Prevention of the distribution of counterfeit products.
3. Elimination or reduction of theft and loss.
4. Reduction of supply chain cost.
5. Elimination of data entry and other tedious manual business process transactions.
6. Increase in order fulfillment time
7. Less time spent in check out lines, as consumers will only have to push their shopping carts in front of the readers.

The predominant downside is the high cost of the RFID hardware. Where tags alone can cost twenty five cents each or more, many retailers won't get much of a return, if any, on their investment.

It's hoped that Wal-Mart, the Defense Department and others will start using RFID, which could cause the prices of the tags to drop to five cents each, making it a more affordable solution for many.

You Can Not Be Sirius Or Xm

Writen by Michael Casamento

I think it was tennis great John McEnroe who made the phrase "You can not be serious" famous, but he certainly wasn't referring to SIRIUS and the latest trend in digital satellite technology... Satellite Radio. Any discussion about Satellite Radio just wouldn't be proper without first paying homage to its digital forerunner, Satellite TV. Since its introduction in 1994 Satellite TV has been the single most successful consumer electronics product in history. It only seems natural that on the heels of such success would come yet another form of digital satellite technology, Satellite Radio.

Satellite Radio squarely addresses the biggest problems associated with current radio technology. FM Radio signals are relatively short range and prone to static. Combine this with a healthy dose of commercials, and you have the makings for some pretty disgruntled listeners.

As far as technology is concerned, Satellite Radio leaves FM in the stone age. Multiple satellites located in geosyncronus orbits above the Earth deliver crystal clear, near CD quality audio signals to wherever you may be. That means you can get in your car and drive across the entire United States while listening to the same radio station. To top it off, your music will never be interrupted by annoying commercials! If you love music, Satellite Radio is a dream come true.

The Satellite Radio scene currently consists of two providers who eagerly compete for your business, SIRIUS and XM Radio. Both companies knew that it wouldn't be easy to convince the public to part with their hard earned cash unless the value of their product was readily apparent. Having the advantage of starting with a blank sheet of paper, SIRIUS and XM have designed their systems from the ground up to be nothing less than state of the art.

SIRIUS operates from an ultra modern facility located at Rockefeller Center in the heart of New York City. Being in New York was an important part of their mission, as this puts them within close proximity to major recording artists, and disk jockeys. Their custom designed and engineered performance studios are frequently visited by top musicians stopping by for live interviews and performances. SIRIUS programming features over 60 music channels with ZERO commercials, along with 40+ specialized sports, news, and entertainment channels.

XM Radio's broadcast center is located in Washington, D.C., and includes a 2,600 square foot performance studio for live recording and broadcasts. It is the largest and most advanced of its kind in the world, where artists from all musical genres come to perform exclusive concerts for XM listeners. For regional broadcasting and location work, the Washington studio is supplemented by studios in New York and at the Country Music Hall of Fame in Nashville. XM also offers over 60 channels of 100% Commercial-Free music, 30+ channels of News, Sports, Talk & Entertainment, and 20+ channels of XM Instant Traffic & Weather.

Although it's in its infancy, Satellite Radio is begining to prove that people are willing to pay for what they currently can get for free. XM and SIRIUS Radio have been growing their subscriber base at a very healthy rate. With its roots in automotive sound, the recent availability of new hardware has truly made Satellite Radio a total solution. Walkman style units now allow you to take Satellite Radio just about everywhere, and sophisticated home units are also available that perfectly integrate SIRIUS or XM Satellite Radio into your home entertainment system.

The future looks bright for Satellite Radio. For those who spend a lot of time behind the wheel, the decision to switch to Satellite Radio can almost be a no brainer. The fees are reasonable, and the service and programming are absolutely top notch. The hardest choice you will have to make is whether to go with SIRIUS or XM Radio. All things in life should be this easy.

The Facts You Need To Know About Satellite Radio Part 1

Writen by Jim Johnson

Time and technology marches on and things that were considered impossible just a few years ago, are now almost routine. That applies to a lot of things in life, but certainly to the way that we are able to listen to radio broadcasting today.

Just a few years ago it was just accepted that if you tuned in to a particular radio station, you would lose reception and clarity if you were driving long distance and you would have to hunt around and find another station instead. It was also accepted that every broadcast would be filed with lots of ads that you didn't really want to hear, just so the radio station could turn a profit.

Well, now there are more choices to be ahd and technology has made a whole new way of broadcasting radio possible. It's called satellite radio and we will try to help you understand a few facts about it, because the more you know about it, the more you will no doubt appreciate what it can do for you.

First of all, conventional radio traditionally only travel around 30-50 miles with any clarity at all, and then they degrade rapidly. Much of that is due to the roundness of the earth and so as the signal goes out it can't follow the contour of the earth and so the signal is lost to the user. Satelliter radio has solved that issue altogether. As it's name implies, the signal is sent from satellites over 20,000 miles above the earth, so there is absolutely nothing that can obstruct the broadcast signal.

There are currently two major players in the US in this new field, Sirius and XM satellite radio. XM has two satellites in orbit and Sirius employs three. They are specifically timed and placed within orbit to maintain constant coverage of the US for about 16 hours at a time. What this means to you is that no matter where you go in the US and no matter what time of day or night, you will not lose reception, and can enjoy the programming that you like uninterrupted.

This feature alone of satellite radio is an incredible advantage over conventional ground-based radio stations. It comes in handy especially for folks who may live in rural areas that get very poor reception from standard radio, and for those that are long distance travelers. There is no hunting for stations as their reception fades. No having to listen to programming that you don't particularly like just because it's the only thing available in a particular area. Just crisp, clean programming all the time.

But there is lots more about satellite radio to be covered in Part 2 of this report.

Dont Get Lost Or Become The Wrong Way Roadster Gps Can Get You Back On Track

Writen by Rene Tse

If you've ever gotten lost on the way to a business or social function, then it's time to consider a GPS system. It can pinpoint your exact location and provide a map that shows you how to get to your destination.

How does GPS work?

GPS measures the satellite signals in proximity to your location. The GPS receiver absolutely needs to know where it is! This happens by receiving signals from a minimum of three satellites. If it wants elevation, then a fourth satellite needs to come into play.

Next, is the high end math; GPS locks onto a position and uses trigonometry to calculate its position. This is measured in latitude and longitude. From that point, as long as it stays locked onto your location, it can provide the speed, distance and that most valued of all things; a map to your destination.

What is the signal accuracy of GPS?

GPS signal accuracy is approximately 50 feet. But some systems go beyond this range.

Ground stations help GPS systems achieve an accuracy greater than 50 feet. WAAS (Wide Area Augmentation System) correct satellite orbital errors. With 25 ground stations in the U.S., WAAS calculates and transmits the corrected data to fixed-position satellites. WAAS-enabled GPS receivers reach accuracies of 10 feet or less.

DGPS (Differential GPS) also has a correction method with its network of towers. DGPS systems achieve an accuracy of between 10 and 20 feet, but the downside is that these systems require an antenna to receive the corrected signal.

What options are there for a GPS system?

You can either choose a dedicated GPS receiver with displays, or a receiver that works in conjunction with your PDA or notebook computer. At the lower end, dedicated receivers with displays show the location and basic maps. Others at the higher end offer downloadable capability so you can receive more sophisticated map configurations from a PC.

Pocket PCs, Palm OS devices and notebook computers also offer GPS receivers combined with mapping programs. GPS devices come built into some PDA mounts offered by Akron and Seidio.

Bluetooth GPS Receiver

The Bluetooth GPS Receiver is a stand alone receiver that can communicate with a Pocket PC or Smartphone. To use the GPS receiver with your Windows Mobile device it needs to have Bluetooth capability, or you can simply add the receiver to the unit with a CF or SDIO Bluetooth card.

You don't have to be exactly near your GPS receiver to use it. This is what is really cool about this receiver. It's very flexible too. You can place it within 30 meters of your other Bluetooth devices and still have full GPS functionality. Even more surprising...it can actually produce a map and location details while inside a clothing item or in a container.

It's convenient too. Before you leave for a trip, you can input where you want to go and have it all mapped out when you depart for your new destination.

Consider these factors when selecting a GPS system:

  • 1. Watch out for lost signals. The GPS signal with a satellite could conceivably get lost in rough or remote terrain, like in a canyon or forest. This can be minimized with a system that continuously monitors 12 satellites.

  • 2. Is the GPS system programmable? What is the data package like? Is it cost-effective?

  • 3. What is the power supply like? Some in-car systems come with their own batteries, while others are dependent on the car itself.

  • 4. Pay attention to interface. Some GPS interfaces run better than others. Find out about their performance from tech journals and colleagues.

  • 5. Look at how the maps and directions are displayed. Do you like the presentation? Is it easy to navigate?

GPS - Gets you on track

Think of GPS as a modern take on that classic refrain heard by car passengers everywhere,"Just ask for directions." Only now, you can ask your very own GPS system without worrying about getting lost.

Canadian Satellite Radio Finally

Writen by Scott Fish

Disclosure: Author is not part of Sirius or CSR.

In June, the CRTC granted satellite radio licenses to two groups - the CBC, which is partnered with New York-based Sirius, and CSR, which is partnered with Washington-based XM.

The federal cabinet has upheld the CRTC's decision to issue two new satellite radio licenses. As part of the deal, all applicants agreed to include more Canadian and French-language material. This is typical of Canadian media regulations and has made headway for the satellite radio push and representation. Groups such as Liberal MPs, Quebecers and other cultural groups did have some opposition to the deal. "In effect, the Americans have won…This is a black day," said Ian Morrison, spokesman for the lobby group Friends of Canadian Broadcasting.

Sirius Canada Inc. and Canadian Satellite Radio Inc. (CSR) say they are pleased. CSR CEO John Bitove said in a statement that his company intends to be a "proud" representation of Canadian business and satellite radio to the Prime Minister, the government and the country.

As per conditions of the licenses, The Canadian Radio-television and Telecommunications Commission (CRTC) will begin holding hearings asking for public input on the new commitments. The decision was made by the CRTC in June however the issue has been a heated one as cabinet debated whether to uphold it. Cabinet had the option to approve it, reject it, or send it back for further review.

As part of the agreement, CSR and Sirius have been forces to increase the French-language influence and broadcasting. Both promise to include 8 Canadian channels, which are half English and half French.

Is Sirius Radio For You

Writen by Douglas Hanna

Sirius Satellite Radio does have some great features. It offers more than 125 commercial-free channels, including 65 devoted to music. Plus, you can continue to listen to the same channels no matter where you are – even as you move from city to city and state to state.

Sirius radio is also a sports lovers dream with channels devoted to all major sports with constant sports talk, game broadcasts, news and score updates. For example, Sirius broadcasts all games of all NFL teams, including the playoffs and the Super Bowl. Sirius also broadcasts more than 1,000 NBA games, as many as 40 NHL games per week, college football and bowl games college basketball, and even English Soccer! While Howard Stern is getting the big buzz right, Sirius also has celebrity-anchored channels with Martha Stewart, Jimmy Buffet and Eminem. In short ,whether your interest is the NFL, hip-hop, Christian music, E! Entertainment, or comedy, Sirius has something for you.

What you need to hear Sirius

There are three things you need to get Sirius satellite radio – a subscription, a receiver and an antenna. You can choose a receiver for you car, your home or both. You can find these receivers at just about any electronics retailer such as Best Buy and Circuit City, as well as online at Crutchfield.com, Amazon.com, and TechforLess. The price of these receivers vary all over the place. Some are Sirius ready, meaning that they play through your car radio's CD or cassette player, while others are Sirius portable and can be moved from the car to your home.

A subscription to Sirius currently costs $12.95 per month or about $155 a year.

The downside

There are a few things to consider before buying a Sirius radio. For one thing, it's never local. In other words, you will never hear local weather, local sports updates, local talk radio or local traffic conditions.

Second, you need to consider how much time you spend in your care. If you spend 3 to 4 hours per day driving around, Sirius might be worth the cost. However, if you're in your car only an hour or less a day, you might not want to spend $155 a year to hear commercial-free music, etc.

Finally, there is no guarantee that those commercial-free channels will stay commercial free forever. Sirius continues to lose money as a subscription-based service, and may eventually have to start charging extra for some of its more popular channels.

In the meantime, if you'd like to experience Sirius radio, you can try it free online - just go to http://www.sirius.com and click on Free Online Trial.

If you want digital radio but don't want to pay for it, there's another technology called HD Radio that enables AM and FM radio stations to broadcast their programs digitally. These digital broadcasts provide listeners with radically improved audio quality, more radio channels through multicasting, and new data services. To learn more about this amazing new technology, just go my Web site, http://www.hd-radio-home.com, for complete details.

Anti Jam Gps

Writen by Lance Winslow

If we go to war with China the first thing they will do is knock out as many of our satellites as possible. Many secret SPY satellites in the Military will be safe now up there and there equipment in their UAVs, ground vehicles and command and control centers because they have special Anti-Jamming GPS systems with bleeding edge top of the line and state of the art counter measure technologies. You are probably thinking to yourself who thinks of this stuff anyways? Well you know men and there toys and when the US Military wants something no matter how seemingly impossible someone will find a way.

This time that someone was a little company Harris Corp that has about $3 billion in annual sales and over 12,600 employees as of yesterday and they have teamed up with another little company; The Boeing Company, maybe you have heard of them. Harris Corp will provide to the net-centric battlespace smart munitions anti-jam technologies. This means no one gets away and no smart bombs go astray and that our enemies have only one option before meeting their maker and that is to pray.

Now you are probably saying to yourself, "Hey self, that would be cool in my SUV!" Just think never lose an XM Radio connection or have to worry about interference on your urban assault vehicles GPS. Indeed that would be cool and it will inevitably become standard equipment on all in-car system by 2010 through the gracious gifts of transfer technologies or hand me down research from the US of A. Never a lost signal or missed tune, you got to love it. Think on this.

The Fantastic Futuristic Features Of The Gps System

Writen by Lyne Doxley

Man has always speculated about what lies beyond his immediate circle of knowledge. Many a journey has been taken and many a new land has been discovered all because of man's curiosity. The uncertainties faced and risks taken in the name of adventures and travel has claimed many lives. Navigation and maps are vital to these activities.

Luckily for us, we live in an age of new and innovative ways for technology to help us and one of them is the GPS system.

Global Positioning System (GPS) is a worldwide navigation system formed from a constellation of 24 satellites and the associated ground stations. There can be more than 24 operational satellites; new ones are launched periodically to replace older satellites.

Each satellite orbits continually about the same ground track (as the earth turns beneath them) once per day, at an altitude calculated to ensure the satellite repeats the same track over all points approximately each 24 hours (actually 4 minutes earlier each day).

There are six orbital planes, equally spaced (60 degrees apart), and inclined at about fifty-five degrees with respect to the equatorial plan. The GPS system uses "man-made stars" as reference points to parse accurate positions to within meters.

The GPS system in it's entirety is comprised of a network of satellites, signals, support personnel, ground based hardware and software, which make possible the establishment of one's precise location on the Earth's surface. The Global Positioning System is funded by and overseen by the U. S. Department of Defense (DOD). While there are many thousands of civil users of GPS world-wide, the system was designed for and is operated by the U. S. military.

The accuracy of location measurements using the global positioning system depends on the GPS receiver. High-end, survey-grade GPS receivers can determine locations precise to within centimeters. But even low-end, handheld consumer receivers, can be accurate to within fifteen meters. GPS receivers have been miniaturized to just a few integrated circuits and so are becoming economical and readily available.

The first commercial global positioning system units were precise for only about 100 meters because the military scrambled the signal--a program called Selective Availability. In the year 2000, the U.S. government removed Selective Availability, improving the accuracy of even basic handheld units to within fifteen meters. Today, with additional information from ground based correction services such as WAAS WAAS (Wide Area Augmentation Service) or U.S. Coast Guard differential GPS beacons, accuracy can be improved even further.
