Geosynchronous Satellites - US Government and Military

This a list of satellites mainly in the series of named 'USA xxx' or carrying the predecessor 'OPS' designations. It is in alphabetical order of Name.

This page is a snapshot and is updated frequently. The more inclined or eccentric the orbit, the larger the error margin of the geosynchronous location. Even the worst case should, however, be within ±3 degrees of reality. Only satellites exhibiting less than 0.25° per day of drift are included.

Appearance in this list does not mean that the satellite is operational or under control at its location. Some older, non-working, satellites have drifted to 'wells' in the Earth's gravitational field and oscillate around that location.
