GPS stands for Global Positioning System. It is a satellite radio navigation system built by the United States Department of Defense. Research on the system began in the 60’s and the first GPS satellite was launched in 1978. It took a while for the entire system to come online but finally on April 27, 1995 it became fully operational. At first, the GPS network was only for military use but in the 80’s the United States government authorized the general public to make use of it too.
The GPS network is composed of:
- Satellites
- Earth Monitoring Stations
- GPS receivers
