A satellite that is used to relay telecommunications information.
A satellite in earth orbit that receives signals from an earth station and retransmits the signal to other earth stations.
A satellite placed in a geosynchronous orbit and rotating with the earth so that the satellite is always in the same spot relative to the earth.
an artificial satellite that relays signals back to earth; moves in a geostationary orbit
a complex device in orbit around the Earth, often two stories tall and with a mass of about four cars, that picks up radio signals from the Earth, amplifies them using solar power, and beams them back to a receiving station on Earth
an artificial satellite stationed in space for the purposes of telecommunications using radio at microwave frequencies
a radio relay station in orbit above the earth that receives, amplifies, and redirects analog and digital signals carried on a specific radio frequency
a spacecraft that orb BROADBAND Satellite Communication Systems by Encyberpedia and Bob
a spacecraft that orbits guide the satellite into orbit and help keep them there
a spacecraft that orbits the Earth and relays messages, radio, telephone and television signals
A spacecraft in orbit around the Earth that transmits telephone and TV signals. The Earth and beyond
An earth-orbiting device that relays communications signals over long distances.
An artificial satellite, usually placed in geostationary orbit used to relay radio transmissions.
Space station that receives microwave signals from an earth-based station, amplifies (strengthens) the signals, and broadcasts the signals back over a wide area to any number of earth-based stations. 9.38- 39
A "relay system" in orbit above the earth's surface for telecommunications signals such as voice, video and data; requires earth stations to transmit and receive the signals at the ground locations.
A space vehicle which receives TV and radio signals and transmits them back to earth. It is located 22,300 miles above earth in a geosynchronous orbit so that it is stationary in relationship to a fixed position on earth.
An orbiting vehicle that relays signals between terrestrial communications stations, a terrestrial communications station and another communications satellite, or other communications satellites.
A satellite used to relay telecommunications signals between two or more points.
Earth-orbiting spacecraft designed to receive and send data.
A satellite designed to act as a telecommunications radio relay and usually positioned in geosynchronous orbit 23,000 miles (35,800 kilometers) above the equator so that it appears from earth to be stationary.
A type of satellite used for communications on Earth by allowing radio, television, and telephone transmissions to be sent live anywhere in the world. Before satellites, transmissions were difficult or impossible at long distances. The signals, which travel in straight lines, could not bend around the round Earth to reach a destination far away. Because communications satellites are in orbit, the signals can be sent instantaneously into space and then redirected to another satellite or directly to their destination.
