communications satellite
- Noun:
- An artificial satellite that relays signals back to Earth: A man-made object placed in orbit around the Earth, designed to receive, amplify, and retransmit telecommunications signals (such as television, radio, telephone, and internet data) between different locations on Earth.
- Moves in a geostationary orbit: Typically, a communications satellite is positioned in a geostationary orbit, meaning it orbits at the same speed as the Earth's rotation, allowing it to remain fixed over a specific point on the equator, providing continuous coverage to a designated area.
- Noun:
- The launch of the new communications satellite will improve internet access in remote regions.
- Television networks rely on a fleet of communications satellites to broadcast live events globally.
- The signal was transmitted via a communications satellite orbiting 22,236 miles above the Earth.
"To be placed in geostationary orbit": This is a common technical description for the standard orbital position of most communications satellites.
- The communications satellite was successfully placed in geostationary orbit, where it will serve the continent for its 15-year lifespan.
"Satellite communications": This is a related term (a compound noun) referring to the overall technology and industry, not the satellite itself. It is listed here as it is a primary context for the target word.
- The company specializes in satellite communications, providing critical links for maritime and aviation industries.
Comsat (n): A common abbreviation for "communications satellite."
- The comsat experienced a temporary outage yesterday.
Relay satellite (n): A synonym emphasizing the signal-relaying function.
- The deep-space probe sent its data back to Earth through a relay satellite.
Geostationary satellite (n): A term highlighting the orbital characteristic shared by most communications satellites.
- A geostationary satellite appears stationary in the sky from the perspective of a ground station.
- Telecommunications satellite: A formal synonym with identical meaning.
- Broadcast satellite: A type of communications satellite specifically for television or radio broadcasting.
Satellite link: A connection established using a communications satellite.
- The news report came through a live satellite link.
Satellite uplink/downlink: The transmission of a signal to a satellite (uplink) and the reception of the signal from it (downlink).
- The broadcast center prepared the satellite uplink for the live concert.
- Low Earth Orbit (LEO) satellite: A newer generation of satellites for communications that orbit much closer to Earth than traditional geostationary ones, reducing signal delay. This is a contrasting concept.
- Constellations of LEO satellites aim to provide global broadband internet, challenging traditional communications satellite models.
