A GPS has 3 components: The first component is the space component (24 satellites) orbiting the Earth, of which 21 are navigation and three backup satellites. The second component consists of the main station at Colorado Springs and consists in 5 tracking stations with 3terrestrial antennas distributed around the Earth, these stations can control the place of each of the GPS satellites, and finally, the user component that comprises the receivers.
