GPS tracking is the surveillance of location through the use of the Global Positioning System (GPS) to track the location of an entity or object remotely. The technology can pinpoint the longitude, latitude, ground speed, and course direction of the target.

GPS trackers connect to a series of satellites to determine location. The tracker uses a process called trilateration which uses the position of three or more satellites from the Global Navigation Satellite System (GNSS) network and its distance from them to determine latitude, longitude, elevation, and time.
