The GPS is a space-based global navigation satellite system (GNSS) that provides reliable positioning, navigation, and timing services to civilian and military users on a continuous worldwide basis -- freely available to all. | |||
It is maintained by the United States government and is freely accessible by anyone with a GPS receiver. | |||
GPS receivers compute their position in the GPS Reference System using satellite technology and based on triangulation principles | |||
GPS was originally developed for the U.S. military, but is now provided as a public service for people all over the world by the U.S. government. | |||
Deployment of the GPS system began on 22 February 1978 with the launch of the first Block I Navstar GPS satellite. Initial Operating Capability was declared in December 1993 with 24 operational GPS satellites in orbit. Full Operational Capability was declared in June of 1995. | |||
