i guess every satellite which hover around the earth is a hovering satellite , they are sent for the purpose of communication , weather forecast etc ... there is no any particular satellite named hovering satellite.

Hovering Satellites

Satellites are man-made objects revolve around the earth for certain scientific purposes. The satellites apparently static in relation to earth are put into such orbits that their orbital velocity cancels the spinning velocity of earth and both becomes synchronized, such satellites are called ‘Hovering Satellites’.

Geostationary Orbits

The orbits in which such hovering satellites appear stationary from the earth are called geostationary orbits.

Explanation of Hovering Satellites

* Hovering satellites are usually situated at the height of about 35600km above the earth. A number of hovering satellites are situated at various parts around the earth for instant communication facilities round the globe.

* Communication satellites provide reliable and continuous telephone and TV transmission throughout the globe and change their position with respect to ground stations.

* Surveillance satellites placed either in geostationary orbit or in lower orbits, gather info about enemy troops and military installations through visual and infrared imaging.

* Weather satellites provide daily info about changing weather conditions expected to prevail in the region.

* Research satellites provide info about earth’s magnetic field and cosmic rays e.g. MRI Skylab.

* Moving satellites do not serve for establishing communication links between different continents as communication through space require these satellites to have
specific position relative to earth for efficient transmission of signals between ground station and a satellite.
