The entire GPS system is an integrated system of 24 satellites that orbit the earth and through the navigational process of triangulation can pinpoint a local anywhere on earth where a GPS product is searching for a signal. A couple of years ago, the government allowed for the creation and everyday use of the system for retail GPS devices. Technology insiders all predict that GPS products will become just as common and such a day to day utility as cell phones are now. In a few years, GPS systems will be incorporated into just about everything and make it incredible hard to loose things; be it cars, dogs, or kids. GPS products and navigation systems can replace all the maps in your car and ensure that you get to your destination on time and with all of your kids in toe. Many GPS products come bundled with mapping software and can give you driving directions, show you different routes to avoid road work, and can help you find your way through a foreign city. In the process of actually driving somewhere, many GPS devices can verbally direct you to the neighboring gas stations, restaurants, and other points of interest in a step by step manner. Most GPS units have varying levels of sensitivity. There are positioning technologies that allow common people to find way around and are generally non-military like. The other category of GPS is military specific with much more detailed tracking and mapping capabilities. The military grade GPS can scan the photograph from a satellite or read a newspaper headline. This amount of precise military positioning will eventually be in the hands of the general public, much like standard GPS did in the beginning. There are many accessories available for GPS products and navigation systems. Systems with voice output are a great help as they do not create the slightest distraction for the driver. Everybody could use one and everybody can use one, because you really do not need any special skill to drive a car with a GPS product or navigation system installed.
