communications satellite

A communications satellite orbits high above the Earth, relaying signals between continents.

Definition
  1. 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.
Usage Examples
  • 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.
Advanced Usage
  • "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.
Variants and Related Words
  • 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.
Synonyms
  • Telecommunications satellite: A formal synonym with identical meaning.
  • Broadcast satellite: A type of communications satellite specifically for television or radio broadcasting.
Related Phrases
  • 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.
Related Concepts
  • 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.
