Communications

Satellite A communications satellite is a man-made satellite that orbits the earth, and is used as a medium to transmit and receive radio, television and telephone signals, as well as data and images. By bouncing signals off the satellite, communication can take place between two places on the Earth's surface that would otherwise be out of range of each other. This technology has enabled world-wide communication, and is used extensively for broadcasting, teleconferencing, long distance phone calls, and for image transmission for remote sensing, among many others. The use of communications satellites has revolutionized the way we communicate, providing a cost-effective and reliable medium for sending and receiving data from virtually any point on the planet.
