The Coarse Analog Sun Sensor (CASS) contains a 2-segment solar cell. Each cell segment generates a short circuit current (ISC) proportional to illumination intensity. These two currents are processed at the spacecraft level to indicate sun angle ∝ and Sun Presence. The CASS solution is Rad hard to more than 100 krad (Si).
