A satellite sends a signal to a ground station, which redirects the signal to the desired location. The ground station receives the signal from the satellite and transmits it to an antenna on Earth. The antenna then sends out radio waves that carry the information in a form that can be received by any receiver tuned to that frequency. The receiver picks up these radio waves, converts them back into electrical signals, and sends them through wires or cables to another device such as a television or computer monitor.
