Abstract: Communication has revolutionized by the Satellites. Its importance and services to human race cannot be neglected. A communication satellite may be looked upon as a big microwave repeater body, where the satellite consists of so many numbers of transponders. Where transponders receive the incoming signal, modifies them and sends back them to the earth station at the receiver end. The satellites work in the operating frequency range of 1 GHz to 50 GHz. The technique with on the satellite communication operates is the FDM. This is the oldest technique but nowadays TDM is also being used, where FDM stands for frequency division multiplexing and TDM for time division multiplexing. As we all know satellite is a heavenly body which moves around the earth in an elliptical or circular orbit to carry on the motion of satellite in circular orbit. The various applications of satellite are weather forecasting, television, radio broadcasting, GPS & internet Communication, etc. Satellite can be used for point-to-point or point-to-multipoint communication is supported.

Keywords: Satellites communication, GPS system, Ground Segment, Control Segment, Space Segment, Telemetry and Tele command.
