how high does a satellite need to be to maintain orbit
High Earth Orbit. When a satellite reaches exactly 42,164 kilometers from the center of the Earth (about 36,000 kilometers from Earthâs surface), it enters a sort of âsweet spotâ in which its orbit matches Earthâs rotation.his special, high Earth orbit is called geosynchronous. A satellite in a circular geosynchronous orbit directly over the equator (eccentricity and inclination at zero) will have a geostationary orbit that does not move at all relative to the ground. It is always directly over the same place on the Earthâs surface.
