Global positioning system (GPS) tracking is the use of satellites along with a GPS device to track the location of a person or object on or near the surface of the earth. GPS tracking requires the use of four or more satellites in a medium orbit around the earth to calculate the position of a tracking device within a fairly accurate degree of proximity. A GPS tracker can take a variety of forms and serve several different functions, but the overall process used by them is mostly similar. The three basic types of GPS trackers are data pushers, data loggers, and data pullers.
