A satellite is something that orbits around a planet, such as a moon, or a man-made object that facilitates telecommunications.
A man-made satellite is a radio relay station that orbits the earth. A complete satellite communications system also includes earth stations that communicate with each other via the satellite. The satellite receives a signal transmitted by an originating earth station and retransmits that signal to the destination earth station(s). Satellites are used to transmit telephone, television and data signals originated by common carriers, broadcasters and distributors of cable television program material.
