GPS stands for Global Positioning System. It is used by individuals, commercial entities and the military for navigational purposes. GPS uses 24 satellites that orbit the earth and send radio signals. The GPS satellites work with a GPS receiver which today can be found in individual handheld units, car navigational systems, boat navigational systems, highly precise commercial products and a wide range of military equipment. Operation of GPS GPS operates using triangulation. Triangulation is a method in which three separate points are measured to calculate location. For instance, in a car’s navigation system, the car’s location is measured by three specific satellites orbiting the earth. Using triangulation, GPS can deliver the location to the receiver within centimeters of its exact spot. It is important to note that GPS radio signals use a specific frequency. There are actually two major frequencies that GPS work on: one is for public, non_military use (1575.42 MHz) and one...
