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. The website provides a spreadsheet containing details of all the satellites, which can be downloaded. Of these, 560 are listed in the database as being at GEO. This includes all orbits and everything down to the little CubeSats, not just satellites in GEO. 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.Īs of May 2021, the website UCS Satellite Database lists 4,550 known satellites. This corresponds to an inter-satellite spacing of approximately 73 km. Some of these satellites are separated from each other by as little as 0.1° longitude. To avoid confusion, geosynchronous satellites that are not in geostationary orbit are sometimes referred to as being in an inclined geostationary orbit (IGSO). Specifically, geosynchronous Earth orbit ( GEO) may be a synonym for geosynchronous equatorial orbit, or geostationary Earth orbit. Popularly or loosely, the term "geosynchronous" may be used to mean geostationary. A satellite in a geostationary orbit appears stationary, always at the same point in the sky, to ground observers. Not included in the list below are several more classified military geosynchronous satellites, such as PAN.Ī special case of geosynchronous orbit is the geostationary orbit, which is a circular geosynchronous orbit at zero inclination (that is, directly above the equator). A number of weather satellites are also present in geosynchronous orbits. Traditional global navigation systems do not use geosynchronous satellites, but some SBAS navigation satellites do. These satellites are commonly used for communication purposes, such as radio and television networks, back-haul, and direct broadcast. This is a list of satellites in geosynchronous orbit (GSO). Further details may exist on the talk page. Please expand the article to include this information. This article is missing information about other geosynchronous satellites.
