GPS receivers are devices that receive signals from orbiting satellites in order to determine the location or geographic position. The applications of the worldwide Position System technology are very big, with GPS receivers working for the aviation, the sea, the military and the average purchaser. The satellites that the receivers depend circle the world twice a day, and they’re prepared in such a way on the orbit, that at any moment of the day, four of them should be present on the plain sky allowing one to find the best location or direction. Although at first, the system was planned for the utilization of the US military alone, it was shortly opened to the public for individual, civilian applications.
