Coarse Analog Sun Sensor (CASS)


The Redwire 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 α and Sun Presence.

The CASS unit is Rad hard to more than 100 krad (Si).
