Gps Satellite Constellation Map

By 1986 18 had been launched into orbit making the system usable for many applications.

Gps satellite constellation map. The gps receiver needs 4 satellites to work out your position in 3 dimensions. Gps satellite positions find bright satellite passes. To ensure this commitment the air force has been flying 31 operational gps satellites for the past few years. While gps is the most prevalent gnss other nations are fielding or have fielded their own systems to provide complementary independent pnt capability.
