A geosynchronous orbit is an orbit around a planet with an orbital period matching the planet's sidereal rotation period. 

This synchronization means that for an observer at a fixed location on [[Earth]], a satellite in a geosynchronous orbit returns to exactly the same place in the sky at exactly the same time each day. In principle, any orbit with a period equal to the planet's rotational period is technically geosynchronous, however, the term is almost always used to refer to the special case of a geosynchronous orbit that is circular (or nearly circular) and at zero (or nearly zero) inclination, that is, directly above the equator. This is sometimes called a geostationary orbit.

[[Orbital Defence Platform]]s in particular make use of geostationary orbits to protect certain ground regions from attack; [[Cairo Station]], for example, orbited directly over the city of Cairo, taking its name. The Athens Station also orbited above the Greek city of Athens. Other satellites orbit in traditional geosynchronous orbits, returning to the same point in orbit every rotation of the [[Earth]].

-A '''geosynchronous orbit''' is an orbit around a planet with an orbital period matching the planet's sidereal rotation period. The term geosynchronous can be used to describe any orbital pattern with a period equal to that of its orbiting body, and in the same direction as the parent's rotation, but is specifically used for orbits with no inclination and a semimajor axis of equal length to the minor axis (i.e. circular). Satellites in geosynchronous orbits appear to maintain their longitude, while their latitude oscillates in a 24-hour period. The geosynchronous orbit over the equator is called the '''geostationary orbit'''. Satellites in the geostationary orbit appear stationary relative to the planet's surface.
