Global positioning system gps constellation satellites the global positioning system gps is a popular satellite navigation system.

Gps satellite constellation map.

The gps receiver needs 4 satellites to work out your position in 3 dimensions. While gps is the most prevalent gnss other nations are fielding or have fielded their own systems to provide complementary independent pnt capability. As of august 2020 75 global positioning system navigation satellites have been launched 31 of which are operational 9 in reserve 3 being tested 30 have been retired and 2 were lost at launch. The united states is committed to maintaining the availability of at least 24 operational gps satellites 95 of the time.

Global navigation satellite system gnss is a general term describing any satellite constellation that provides positioning navigation and timing pnt services on a global or regional basis. A map of the 88 constellations of the night sky projected into either equatorial or galactic coordinates.

A constellation of more than two dozen gps satellites broadcasts precise timing signals by radio allowing any gps receiver to accurately determine its location longitude latitude and altitude in any weather day or night anywhere on earth. Rockwell international now a division of boeing was contracted to build gps satellites beginning in 1974. The global positioning system gps originally navstar gps is a satellite based radionavigation system owned by the united states government and operated by the united states space force. By 1986 18 had been launched into orbit making the system usable for many applications.

Gps satellite positions find bright satellite passes. The constellation requires a minimum of 24 operational satellites and the official target count is 33.

To ensure this commitment the air force has been flying 31 operational gps satellites for the past few years.
