Geosynchronous orbit (Earth-5875)

A geosynchronous orbit (sometimes abbreviated GSO) is an orbit around a planet with an orbital period that matches the planet's rotation on its axis. Over the course of a day, the object's position in the sky traces out a path whose precise characteristics depend on the orbit's inclination and eccentricity. Satellites are typically launched in an eastward direction.

Orbital defense platforms and space stations use geosynchronous orbit around the planet they orbit.
