Earth Station

Welcome to the Cal Poly Earth Station! Commonly called a “ground station,” an earth station is a radio station built specifically to talk with satellites orbiting this planet. The purpose of the site is to spread the word on how to build an earth station. Many schools launching CubeSats have not put much energy into their earth station, thinking that it will be built after the satellite is finished but before it is launched. This is the wrong way to think about building an earth station, because how is the mission going to be considered a success if the satellite can’t be heard or talked to? It also takes a long time to train operators in the art of communicating with an object traveling at 8 km/sec. The earth station is the most important part of the whole mission.
