ARTIFICIAL COMMUNICATION SATELLITES
Artificial communication satellites are placed in an orbit around the Earth. They relay radio and television signals around the curved surface of the Earth and thus serve the purpose of intercontinental radio and television transmission. There are two types of satellites in the orbit: active and passive. As for active satellites, they are used to receive, amplify, and retransmit signals being sent for the purpose of communication. The function of passive satellites is only to reflect the transmitted signals from the surface of the Earth.
