Information is transmitted through artificial satellites called communication satellites. Communication satellites are used for telecommunications through signals transmitted from ground stations located on earth. Earlier, communication satellites traveled in a fixed orbit around earth but modern communication satellites can change their orbits. Television and radio programs, network are all made possible by satellite communication. Communication satellites are also useful in mobile applications to ship and airplanes. Digital data and telephone circuits are also relayed and carried through communication satellites.
