Satellite is any body that revolves around another. Thus, the hangers-on or the parasites who would receive their sustenance from another person were called the satellites. In the celestial sphere, any body which revolved around another is called a satellite of the latter. In a more restricted use, bodies around a planet were called satellites, and prior to 1957 when Sputnik was launched by USSR, all satellites were natural bodies. Now, there are thousands of artificial satellites revolving around earth. The satellites have been used for a number of uses; communication is just one of them.

Satellite communication is being done through various types of satellites. There are the Geo-Stationary satellites that remain fixed relative to a coordinate on earth, and hence may be used to relay back information. Thus, live television feeds, telephone calls, and other communication services are provided through such satellites. There are the Geo-Information systems where a number of satellites provide geographical information, like location coordinates, information on speed and distances covered, eye-in-the-sky facilities, etc. Thus, the American GPS, and the upcoming European Galileo, are among such systems.

Lately, internet and intranet communication is being provided through such satellites. Access to internet and intranet becomes possible through such systems anywhere, within the service area. This results in true mobile networking. There is the problem with latency time, as the data beam has to travel a lot of distance (first to the satellite, and then back again), which results in a slight delay voice communication is usually not done with satellite communication where latency time is a factor. Satellite TV provides access to TV channels even without the presence of TV towers.

In this section of the directory, we provide links to various satellite resources, like satellite TV, satellite internet, etc; to directories of satellite services, guides and a lot more.
