communications satellite

(Telecommunications) an artificial satellite used to relay radio, television, and telephone signals around the earth, usually in geostationary orbit

communica′tions sat`ellite

a satellite designed to facilitate radio, telephone, and television communication by retransmitting the signals it receives while orbiting the earth.

com·mu·ni·ca·tions satellite

An artificial space satellite used to transmit signals, such as television and telephone signals, from one ground station to another.

communications satellite

An orbiting vehicle, which relays signals between communications stations. There are two types: a. active communications satellite--A satellite that receives, regenerates, and retransmits signals between stations; b. passive communications satellite--A satellite which reflects communications signals between stations. Also called COMSAT.
