A satellite is an object that orbits around a planet, for example, a moon. Man-made satellites can facilitate [telecommunications]] or serve other functions.
An example of 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 other data signals originated by common carriers, broadcasters and distributors of cable television program material.
In history, the term "satellite nation" refers to those nations under the sphere of influence of the Soviet Union, or under the "Iron Curtain".
