Orbital mechanics confirms that geosynchronous orbits can have non-zero inclinations or eccentricities, meaning they are not strictly geostationary (which requires a zero-inclination, circular equatorial orbit).

The analysis

A geosynchronous orbit is any orbit with a semi-major axis corresponding to a sidereal day, while a geostationary orbit is a specific subset of geosynchronous orbits that are circular and directly above the equator (zero inclination). Satellites in inclined geosynchronous orbits (IGSOs), such as those in the BeiDou constellation referenced in papers [5] and [9], match the period but trace out figure-eight patterns on the ground, proving the existence of geosynchronous orbits that are not geostationary.
