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 under control at its location. Some older satellites have drifted to 'wells' in the Earth's gravitational field and oscillate around that location giving the appearance of an intentionally geosynchronous orbit. This includes a number of spent rocket bodies.

Other lists of USA and OPS geosynchronous satellites in different orders of presentation can be found from the left hand menu.

For these 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.
