How do satellites work? - Explain that Stuff

Relaying radio waves from one place on Earth to another. Catching signals that fire up to them from a ground station (an Earth-based satellite dish). Amplifying the signals so they have enough strength to continue (and modifying them in other ways). Bouncing the signals back down to a second ground station somewhere else. Orbiting Earth when their speed is balanced by the pull of Earth's gravity. Consisting of the communications system, the power system, and the propulsion system. Transmitting or uplinking a signal from an Earth station to a satellite. Receiving and amplifying the signal and retransmitting it back to Earth. Beaming out a radio-wave signal toward Earth.
