EyasSat is a fully functional nanosatellite designed for teaching spacecraft systems engineering in the classroom and laboratory. EyasSAT was co-developed between the U.S. Air Force Academy and Colorado Satellite Services. EyasSAT demonstrates six traditional satellite subsystems of a satellite bus: Structural, Electrical Power (EPS), Data Handling (DH), Communications (Comm), Attitude Determination and Control (ADCS), and Thermal subsystems.
