List of satellites in geosynchronous orbit
Posted: Tue Mar 07, 2023 7:23 am
This is a list of satellites in geosynchronous orbit. These satellites are commonly used for communication purposes, such as radio and television networks, backhaul, and direct broadcast. Traditional global navigation systems do not use geosynchronous satellites, but some SBAS navigation satellites do. A number ofweather satellites are also present in geosynchronous orbits. Not included in the list below are several more classified military geosynchronous satellites, such as PAN.
Listings are from west to east (decreasing longitude in the Western Hemisphere and increasing longitude in the Eastern Hemisphere) by orbital position, starting and ending with the International Date Line.
Some of these satellites are separated from each other by as little as one tenth of a degree longitude. This corresponds to an inter-satellite spacing of approximately 73 km. The major consideration for spacing of geostationary satellites is the beamwidth at-orbit of uplink transmitters, which is primarily a factor of the size and stability of the uplink dish, as well as what frequencies the satellite’s transponders receive; satellites with discontiguous frequency allocations can be much closer together.
