GPS or Global Positioning System is a fully functional Global Navigation Satellite System. This system uses an artificial constellation of 24 medium Earth orbit satellites. These satellites transmit microwave signals, thus enabling a GPS receiver to determine its location, speed, direction and time. This system was developed by United States Department of Defense and was named as NAVSTAR GPS which was given by Mr. John Walsh. NAVSTAR is not an acronym, as is widely believed.

This satellite constellation is managed by United States Air Force 50th Space Wing. The cost is approximately 750 US dollars every year, including the maintenance cost, replacement, research and development. After shoot down of Korean Air Lines Flight 007 in the year 1983, a directive was issued which made the GPS available for civilian use and has been used extensively since then. It has become a very useful tool for making maps, surveying landscapes, commerce and many scientific uses. It also provides time reference which can be used in many applications which include study of earthquake and telecommunication network synchronization.

A GPS receiver simply calculates the distance between itself and three more GPS satellite. Each satellite has an atomic clock in it continually transmits certain data containing its exact time, location of the transmitting satellite and the almanac. The receiver then measures the reception time of the signal. Thus the distance to each satellite is known. Knowing three such distances, a trilateration is formed. By using a fourth satellite, need for a clock at receiver is avoided.

The Global Positioning System is used in a variety of Military and Civilian Applications. It allows soldiers find their objectives in a dark or completely unfamiliar territory and coordinate troop movement and supplies. GPS receivers which military personnel use are called Commanders and Soldier Digital Assistants. A combination of GPS and communication through radio enables real time vehicle tracking.

It is also used in marking targets as hostile and enables the precision guided munitions to allow them engage these targets with high accuracy. Air to Ground roles of military aircrafts use GPS to find targets. GPS also allows targeting for military weapons like ICBMs, Cruise missiles, precision guided missile. Artillery based projectiles are embedded with GPS receivers and can withstand forces up to 12,000G. These are used for 155 mm Howitzers. Any Downed pilot can be easily located if he has GPS receiver. It is widely used by military for reconnaissance and mapping. Some GPS satellites also have nuclear detonation detectors.

GPS helps civilians a lot in surveying and navigation. Its ability to calculate local speed and orientation is extremely useful. Time transfer is possible because of its capability to synchronize clock. A widely used example of use of GPS is CDMA digital cell phone. Each base uses a GPS timing receiver to synchronize the codes with different base stations and thus making it easy inter-cellular hand off and thus support emergency phone calls and other many applications. GPS equipment has also revolutionized tectonics by measuring the fault motion during earthquakes.

The two GPS developers, Ivan Getting and Bradford Parkinson have received national academy of Engineering Charles Stark Draper prize during year 2003. Roger L Easton received National Medal for technology on February 13, 2006. Other similar tracking systems are Beidou, which has been developed by China and is proposed to be expanded into COMPASS; Galilieo, which is been developed by European Union along with many other countries like India and China; GLONASS, which is been developed by Russia is fully available in partnership with India; IRNSS is India`s proposed regional system and QZSS which has been proposed by Japan.

Customer Review: Holux GPS Receiver
I have an HTC Touch and until the gps update comes out I needed a gps receiver. I picked the Holux GPSlim 240 becasue of price and other reviews on amazon. I was able to connect the receiver to my phone with no problems and so far (over a month) I have had no problems. The only issue I have found (not the receivers fault)is that while using the BT Receiver I can't use my BT Headset. I think you might need some type of hub or router to use both. Because of this if you use a service like TeleNav you can't hear your directions via your headset. I'm sure this is an issue that will be the same with any BT Receiver connected via BT.
Customer Review: Got it. Worked for about 9 months.
I got this for Christmas of '07, for use with the TOM TOM PDA for my business travel and BeeLine software for Geocaching on my Ipaq RX3715. Initally it worked great. However, when it gets warm, it looses it's bluetooth connection. Now when I mean warm, I mean, 70 degrees. I live in Minnesota, and yes, it does get above 70 here. So having a device that stops working when the car (finally) gets warm is less than ideal. Now I suspect that when it stops broadcasting bluetooth, it's still tracking sat. data, as the sat light continues to blink, but that just makes it fustrating. The manual has a warning on high temperatures, as I recall. I'm shopping for something a more reliable, and will go to something with replacable batteries.

The true joy of the motorhome experience is the blend of roughing it with the enjoyment of the comforts of home. With a motorhome Winegard Satellite receiver, your favorite show is part of the experience.

The Winegard Sensar III Batwing motorhome antenna is the most popular motorhome antenna on the market today. It was first developed by the Winegard Company in the early 1970's for use in motorhomes for reception of television signals. In recent years, Winegard has been a leader in technological advances that have brought not only television to motorhome users, but also full satellite TV reception.

The Winegard Satellite systems use GPS (Global Positioning Satellite) technology to provide satellite TV reception to your motorhome both when parked and also when moving. The systems use the GPS to keep the antenna directed toward the nearest satellites when the motorhome is in motion providing reception to your passengers. The in motion satellite receivers are small domed units that fit easily on the top of the motorhome.

The MV-2222 Winegard In Motion Satellite Reception system is the top of the line in this mobile technology. At a cost of just over two thousand dollars, it brings both Dish Network and Direct TV satellite semotorhomeice to your motorhome. The system is simple to operate with not much more than an on/off button. It has the ability to handle to separate signals at the same time, so that a family can be watching two shows on two different TV's at the same time. This is the ideal situation for the larger family.

Although the GPS controlled in motion systems represent state of the art, there are a wide variety of other options for the motorhome owner. Winegard makes small dish type satellite receivers that can be mounted when the vehicle is parked. These antennas are relatively inexpensive and they are not difficult to mount and tune for satellite reception. In most cases, the only information that you need is the local Zip Code where you are parked to tune the antenna.

The attraction of the motorhome experience for many people is the ability to bring the comforts of home on the road. Television plays an important role in informing and entertaining people in today's society and there is no reason to be without it while on the road in your motorhome.

Customer Review: Pioneer AVIC-D3
The Pioneer AVIC-D3 is a great after market In-Dash GPS Navigation System. The multitude of features and additional accessories make this system a must have for mobile video/navigation enthusiasts. As with most "all-in-one" type technologies, it does take a while to get used to the interface and menus. Though once you become familiar with them, which doesn't take much time at all, you'll probably find yourself wanting to cruise around just for the heck of it. One slight annoying design flaw is "the system's single disc slot means that users will constantly have to switch between navigation discs and media sources to make the most of its many features." But if this is not of a particular concern to you, then you'll be generally satisfied with this product.
Customer Review: Good System for the price
First off, if you plan to use the Navigation system heavily AND a CD/DVD heavily as well, think about it! I bought this system in the last week and I was able to test it thoroughly this past weekend. Thegps88756 is a very good beginning of the line model and for the price it is going for, even with all the bells and whistles, it is a very good product. If you buy it at the current price from amazon you will get the AVIC-D3($594.95) the bluetooth($94.95) the iPod Cable($15.45) and the remote($13.80-if you need it, my package already included it) totaling for less than $720. Paying $700 for hardware you get navigation, DVD playing capabilities (video plays only when the car is moving less than 10MPH-unless overridden), iPod integration, cell phone integration (handsfree mandatory in CA beginning summer 2008), you can also get satellite radio and traffic if you want. It is a very complete system and you can also expand it by installing head rest monitors or flip down monitors, rear-view camera, amplifiers, and then list can go on and on. As far as comparing this product to others in the market...it has it's limitations. It isn't as complete as other systems could be, but the price makes those things be forgotten about. Cons: 1) It has a limitation on the media loaded. You have one slot for CD/DVD/Navi, so if you want to have a DVD all the time inside your unit, then pretty much forget about Navigation. If you are going to use Navigation all the time, then maybe this system is not the one for you. If you have an iPod however, you can have plenty of music from there without the need for a CD (plus you can play your videos from the iPod too, however you need to manually select them). In my case, I would like to have two DVD slots where I can get to keep the navigation disc inside and I can get an extra slot so I can put music videos to listen to (music from DVDs is much richer than from CDs or iPod) or have it free for a CD. Juggling discs isn't something I look forward to when I'm even starting my drive, even less if I was driving. 2) The screen size is smaller based on its big buttons (relatively speaking) and the CD slot which is visible. I am unsure what the others are in comparison, but seeing them side to side the AVIC-D3 seems to be dwarfed. 3) Programming and usage of the unit is not completely easy or intuitive. I have not been able to program the 150+ entries from my address book into the nav unit since my phone will only do one by one. The phone needs to be disconnected from the unit in order to do this 4) Lack of tilt feature. Some units allow some tilt so that the glare can be reduced. I am unsure of the tradeoff that exists (on the one hand it could brake and make it unusable, on the other, there's no tilt). Pros: 1) Very affordable compared to others. With less than 700, I was able to purchase the system, the bluetooth, iPod connection, and a remote (which I don't know if I'll use, but it's there for now). Other systems (the next one up) went for much more, two times more than this one. 2) Although some of the more intricate programming is, well, more intricate and hard, most things are very easy to get to. You'll get how to program your cell phone and once you have done it once, you really don't need to do it. Playing a DVD, CD, out of the iPod, radio (even programming the stations) isn't hard. Using the navi is very intuitive, keep pressing the Menu button if you need to do something and press Map if you need to get back to the map. 3) Has everything you need, or most of it anyway. 4) Expandable. You can have other screens connected to it, amplifiers, camera, satellite radio (XM & Sirius). I am unsure whether you can have HD Radio or if a DVD changer is currently available or if it will be available, but a DVD changer would be a great addition for the system. In short: I have the system and it works for me, it has what I need at an affordable price with expandability. At this current time, I would say I would buy it again, although I would look to see if there was a possibility to get one with 2 discs for a comparable, or even a little more expensive. I would NOT get it if: I had long drives to difficult locations where I don't know where I'm going and I was carrying kids who would be watching DVDs. Hope this helps getting you the best system for you!

Satellites orbiting along a precise path send signals to earth. This enables GPS technology to pinpoint a person's exact location, and display it on a satellite map. The technology is used in cars to help drivers choose the best route to their destination.

Audiovox, the manufacturer of GPS systems, claim that their more than 40 years experience in the wireless industry has helped to insure best value for money from the GPS system manufactured by them.

The Audiovox GPS receiver uses the satellite signals to calculate the latitude, longitude and altitude at which a user is. This is known as the 3D position. Other calculations such as the vehicle's speed, distance from its destination, etc. are also calculated.

The signals are low power radio signals, designated L1 and L2. The L1 frequency of 1575.42 MHz in the UHF band is used by Civilian GPS. The signals pass through plastic, glass and clouds, but not through buildings or mountains.

Audiovox has innovated, to introduce a Real Time Traffic module which is absent in conventional navigation systems. A car owner can activate this module by buying a simple hardware addition, and paying a one-time activation fee and a low subscription.

The Audiovox Electronics NVX226 3 Portable Navigation car navigation system features 9 function keys, TFT Screen with clear voice and visual instructions. It calculates the estimated time of arrival, distance to go, time to go, and miles per hour.

This model comes with a 1 GB flash memory with full U.S. mapping, turn by turn voice prompts, a built-in rechargeable battery, a windshield mounting bracket, a cradle with a built-in speaker and Canada mapping available on separate CD, if needed.

To get accurate positioning from the GPS system, in your car, you should use an external amplified antenna in your car, which will also give you a full sky view. However try using the GPS system, without an antenna, to begin with.

Most modern GPS receivers don't need one. To provide for the possibility that you might need it in future, make sure there's an external antenna port in the unit you buy.

Customer Review: Great Scanner but poor tech support
Great Scanner but poor tech support from Uniden. Had to send out to get programed from scannermaster.
Customer Review: Great scanner if you are willing to spend extra!
This is a fantastic scanner. It has some really neat features if you are willing to spend that much. I suggest buying a USB cable to program it with because the cable it comes with does not fit into many new computers. Otherwise, no other complaints! Great scanner!

I have been meaning to write about the Global Positioning System, otherwise known as GPS, that "Santa gave us" this past Christmas.

A GPS is a portable travelling device for your vehicle, while on foot, or even during your bike ride in the trails. It is compact enough to fit in your hand. The GPS communicates with satellites and guides you to your location. Whether it's local or global, it can get you there, as long as you have the required model. Basically, it's like having Mapquest available to you at all times without having to print out your directions, plus more!

My husband had always wanted one, and with me not being very familiar with these gadgets, I thought it as "Just boys and their toys". After doing much research, we decided on purchasing a Garmin Nuvi 250 over the TomTom One. Just a quick comparison, TomTom One did not seem too user friendly, in addition, it had too much on the screen. In some cases it can get confusing while driving when you have too much to look at. Where as the Garmin is nice and simple, first point of screen tells you what you want to know and if you would like to know about additional information such as: your speed, distance, etc, then a simple touch screen button can take you there. Also, TomTom uses TeleAtlas maps that are intended for European navigating. Garmin, in my opinion, is more users friendly over the TomTom, and it uses Navteq mapping, intended more for North America.

The Nuvi 250 is one of the lower models and it doesn't have all the bells and whistles. It does your basic navigating and just a little bit more. We got ours for roughly $330.00 (in 2007); this includes taxes and a two-year warranty. Included in the box along with the device are the instructions, car charger, and a mount for attaching it to your dashboard or front window shield while driving. The Nuvi is also ready to use straight from the box as is. No pre-charging needed, just plug the charger into the lighter outlet and you're set. We also purchased a simple case for $29.99 to protect the screen, since it is touch sensitive. This can be found at Best Buy. It's a good idea to maintain your device if you plan to invest a few hundred dollars.

Surprisingly, I too use it, probably more often than he does! The Garmin Nuvi 250 is great to use locally, for long driving trips, and any other types of travelling. You have the option of setting the mapping to automobile, bike, or on foot. Using this GPS saves so much more time because you don't have to worry about getting lost. It calculates the amount of time it will take to get you to your destination. If you bump into any traffic it re-calculates your estimated arrival time. Even if you miss your turn, it will automatically re-calculate your trip and provide you with a detour. This particular model tells you how long you have until you make your next turn and which side your destination will be, whether it's left or right. For example, it will say, "turn right in 300 meters", "arriving at destination on right, in 100 meters", and on top of the screen itself, it will let you know what the name of the street is. You can also change the voice of the commentator from an American to British accent. We have ours as British to add some spunk! Higher models will actually say the street name as opposed to just saying the distance. We didn't find this to useful for us; we thought we could take a quick look at the screen if we need to know what the street name is. For an extra hundred dollars it wasn't worth the spend.

If you have the extra two to three hundred bucks to spend, you can expect additional features like MP3, Blue Tooth Technology, added memory, and traffic updates. Keeping in mind, that a GPS is intended to guide you with your travels, not music. A security feature that I found quite interesting was, when an access code is applied, the device will ask you to hold up the GPS outside in order for it to search the satellites and this becomes your security identity location. In other words, if you are at a restaurant and so happen to forget your access code or you end up blocking it, you must go to your security location and it will unlock it for you there. If you had been at a friends' house when you applied this code that would have been your security location. The only downside to this is, having to drive out of the way to unlock it. Then again, no one else would be able to use your GPS if it becomes lost or stolen, unless they know your security location.

Garmin provides you with thousands of points of interests (POS). This is my favourite part of the GPS. All you need to do is enter what you are searching for and it gives you a list of items. In my case, I love to enter "shopping" and it shows me a list of merchants that are nearby. This is particularly great when we're out of town and I'm not too familiar with the area. Along with shopping centres, are restaurants and foods; there are hundreds of options to choose from! There are plenty more of POS, these are just the ones that I use a lot. For those who need it, the Nuvi 250 can also store pre-set routes. When you have a certain route everyday, just select your favourite route and you're on your way! Other features consist of an SD card slot for downloading additional maps from the Internet or for viewing a slideshow of pictures. Personally, I don't understand why they would have a feature to view pictures but it's there.

The only negative thing that I can think of, in my case anyway, is that I rely too much on the GPS that I don't get to know the streets and figure it out for myself. So, when there comes a time that I won't have my navigator on hand, I'll be completely lost! Otherwise, I'm so glad my husband wanted one, because I benefit from it too! Of course, this is just my opinion; you'll have to try it out for yourselves.

I would recommend the Garmin Navigator to anyone who is interested in purchasing a GPS.
