I) The house component made up (nominally) of 24 satellites in orbit across the Earth (above 20000 km). These knowledge are then formatted as up to date navigational messages for each satellite.Up to date knowledge are then sent on an uplink to each satellite from Earth antennas.
These remote stations are capable of pursue and monitor the place of every of the GPS tracking stations transmit the info obtained from satellites to the main control station that then calculates the very precise orbits of the satellites. The designation Navstar GPS means: navigation system by timing and rating International Positioning system.
