Coast earth station

A coast earth station is a special place on the Earth where people use big machines – called antennas – to send and receive information to and from something far away in space called a satellite.

Just like you use a telephone to talk to your friends far away, people use the coast earth station to talk to satellites that are very far away in space. The satellites are used to send all kinds of information, from TV shows and movies to pictures and even phone calls.

To make this possible, the antennas at the coast earth station send signals that travel through the air and reach the satellite. The satellite then sends back the information using the same type of signal. This way, people can send and receive information from anywhere on the planet to satellites in space thanks to the coast earth station.
