| Geosynchronous Satellites - Meteorology by Longitude
This a list of meteorological satellites currently in geosynchronous orbit and shown in order round the equator. Some are multi-purpose satellites (eg India's Insat 3D) where the meteorological sensors are only part of the payload.
Appearance in this list does not imply that the meteorological payload is still operating.
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 giving the appearance of an intentionally geosynchronous orbit.

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