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 order of geographical location round the equator.

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.

For the satellites that do not have formal published elements, thanks go to the radio and visual amateur satellite trackers for observing, and particularly to Mike McCants for archiving the derived orbits.
