geostationary orbit

Physics

See synchronous orbit.

Astronomy

A circular orbit 35 900 km above the Earth’s equator, frequently used for communications satellites. A satellite in geostationary orbit moves at the same rate as the Earth spins, completing one revolution in 24 hours, so that it always remains at the same point above the Earth’s equator. See also synchronous orbit.

Space Exploration

The circular path 35 900 km above the Earth's Equator on which a satellite takes 24 hours, moving from west to east, to complete an orbit, thus appearing to hang stationary over one place on the Earth's surface. Geostationary orbits are used particularly for communications satellites and weather satellites.

Geology and Earth Sciences

A satellite orbit in which the satellite travels on the equatorial plane in the same direction as the rotation of the Earth at a height of about 36 000 km (more than 5 Earth radii) above the equator. Its orbital period is exactly one sidereal day and therefore the satellite remains vertically above a fixed spot on the surface of the Earth. At this height it has a view of almost the whole of one hemisphere. The possibility of such an orbit was first suggested by Arthur C. Clarke, for whom the orbit is sometimes named. Compare geosynchronous orbit; low Earth orbit; medium Earth orbit.
