High above Earth, in the crowded expanse of geosynchronous orbit (GEO) some 22,300 miles up, a set of American satellites quietly keeps watch. These are the Geosynchronous Space Situational Awareness Program (GSSAP) satellites – often dubbed “neighborhood watch” satellites – and they form a covert but crucial line of defense in space. Born in secrecy…

Definition and How Geostationary Orbit Works A geostationary orbit (GEO) is a circular orbit around Earth’s equator at approximately 35,786 km altitude (about 22,236 miles) where a satellite orbits once per sidereal day (~23 hours 56 minutes) in the same direction as Earth’s rotation en.wikipedia.org esa.int. This precise altitude and orbital period make the satellite…
