This is the 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 of weather 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.
Note that some of these satellites are separated from each other by as little as 1/10 of a degree longitude. While that may seem like very little separation, and it is, at geosynchronous altitude (nearly 36,000 km), 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.

Famous quotes containing the words list of, list, satellites and/or orbit:
“Every morning I woke in dread, waiting for the day nurse to go on her rounds and announce from the list of names in her hand whether or not I was for shock treatment, the new and fashionable means of quieting people and of making them realize that orders are to be obeyed and floors are to be polished without anyone protesting and faces are to be made to be fixed into smiles and weeping is a crime.”
—Janet Frame (b. 1924)
“Modern tourist guides have helped raised tourist expectations. And they have provided the nativesfrom Kaiser Wilhelm down to the villagers of Chichacestenangowith a detailed and itemized list of what is expected of them and when. These are the up-to- date scripts for actors on the tourists stage.”
—Daniel J. Boorstin (b. 1914)
“To the Japanese, Portugal and Russia are neutral enemies, England and America are belligerent enemies, and Germany and her satellites are friendly enemies. They draw very fine distinctions.”
—Jerome Cady, U.S. screenwriter, and Lewis Milestone. Peter Voroshevski (Howard Clinton?)
“The human spirit is itself the most wonderful fairy tale that can possibly be. What a magnificent world lies enclosed within our bosoms! No solar orbit hems it in, the inexhaustible wealth of the total visible creation is outweighed by its riches!”
—E.T.A.W. (Ernst Theodor Amadeus Wilhelm)
