A
geosynchronous satellite is a
satellite in
geosynchronous orbit, with an orbital period the same as the Earth's rotation period. Such a satellite returns to the same position in the sky after each
sidereal day, and over the course of a day traces out a path in the sky that is typically some form of
analemma. A special case of geosynchronous satellite is the
geostationary satellite, which has a
geostationary orbit – a circular geosynchronous orbit directly above the Earth's equator. Another type of geosynchronous orbit used by satellites is the
Tundra elliptical orbit.
