gps

GPS is an acronym for Global Positioning System. The system was developed in the 1980s by the Department of Defense for the United States of America. Part of a Global Navigation Satellite System (GNSS), GPS was intended to provide the United States with a system to provide constant information to a user's precise location, the time, and velocity anywhere on Earth.

A network of between 24 and 32 satellites rotate around the globe to provide constant support. In order for any information to be accurate, the GPS system needs at least four satellites to fixate on any one user (located by a receiver unit). Three satellites work to triangulate a user's location, while another satellite works to calculate the correct time the location coordinates were measured. Other satellites and land-based units also work to provide more calculations to increase accuracy and reduce error. Vehicle tracking devices that run on GPS technology have become increasingly popular in the auto industry.

Garmin and Trimble are makers of the more popular and advanced GPS receivers available.
