The GPS control segment consists of a global network of ground facilities that track the GPS satellites, monitor their transmissions, perform analyses, and send commands and data to the constellation.
Most GPS receivers consist of three basic components: (1) An antenna that receives signals and, in some cases, has an anti-jamming function. (2) A receiver processor unit that converts wireless signals into usable navigation solutions. (3) Control/display unit that displays location information.
The third signal is also sent from the satellite to the receiver. This signal contains data about the state and position of the satellite. The second part of the GPS system is a ground station that consists of a receiver, an antenna, and communication tools for sending data to the data center.
