What Are Satellites Used For Communication

Satellite communication the use of artificial satellites to provide communication links between various points on earth.

What are satellites used for communication.

It creates a communication channel between a source transmitter and a receiver at different locations on earth communications satellites are used for television telephone radio internet and military applications. A number of weather satellites are also present in geosynchronous orbits. There are about 2 000 communications satellites. Learn more about satellite communication in this article.

Satellites communicate by using radio waves to send signals to the antennas on the earth. This is typical of broadcasting satellites and of satellites used for distributing television signals to terrestrial broadcasting stations. Satellite communications play a vital role in the global telecommunications system. A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder.

A satellite is a moon planet or machine that orbits a planet or star. This is a list of satellites in geosynchronous orbit gso these satellites are commonly used for communication purposes such as radio and television networks back haul and direct broadcast traditional global navigation systems do not use geosynchronous satellites but some sbas navigation satellites do. The services provided by satellite communications are voice and video calling internet fax television and radio channels. Communication satellites are designed to relay several or more usually many signals simultaneously.

In some cases there may be a separate transponder for each carrier. A broadcasting satellite system is a type of communication satellite service that distributes video and audio stream via satellite which also services direct to home satellite television. Satellites provide in flight phone communications on airplanes and are often the main conduit of voice communication for rural areas and areas where phone lines are damaged after a disaster. Satellites also provide the primary timing source for cell phones and pagers.

Satellite communications is the use of satellite technology in the field of communications.
