The third element of GNSS is the user segment. The ground control stations analyze the signals they receive and transmit orbit and time corrections to the satellites in the constellation through data uploading stations. The second element of GNSS is the control segment, powered by an earth-based network of ground control stations that function as GNSS receivers. Each satellite in the GNSS constellation sends out a signal that identifies it and shares its time, orbit, and status. The space segment refers to the network of satellites, called constellations, that orbit 20,000 kilometers above the earth.
