geostationary satellite

A Dictionary of Weather

Storm Dunlop

geostationary satellite 

An artificial satellite in an orbit 35  900 km above the Equator, at which altitude it completes one orbit in the same time as one rotation of the Earth (i.e. 24 hours). It thus remains (almost) perfectly stationary above a specific point and has a field of view covering approximately one-third of the Earth's surface (Plates 14 and 15). The meteorological satellites in geostationary orbit include the GMS, GOES, and Meteosat series. By international agreement, when a satellite reaches the end of its life it is moved to another (usually higher) orbit to allow the orbital site to be reused.
