Definition of geostationary in English:



  • (of an artificial satellite of the earth) moving in a geosynchronous orbit in the plane of the equator, so that it remains stationary in relation to a fixed point on the surface. This orbit is achieved at an altitude of 22,300 miles (35,900 km) above the earth. It is used by communication and meteorological satellites.

    • ‘Finally uplink stations send the signal to three geostationary satellites that relay it back for reception by end-users on the ground.’
    • ‘Once in geostationary orbit above the equator this satellite will provide a wide range of high-speed telecommunications services for North America, South America, Europe, North Africa and the Middle East.’
    • ‘Egnos consists of three geostationary satellites and a network of ground stations for the transmission of a signal containing information on the reliability and accuracy of the positioning.’
    • ‘He states that geostationary satellites must violate Kepler's first law, because they must have circular orbits when the first law demands that orbits be ellipses.’
    • ‘Three special satellites located in geostationary orbit above Europe transmit a GPS-like signal that improves the GPS accuracy down to 1 to 2 metres.’
