Spinning Sun Sensors

Adcole Spinning Sun Sensors are uniquely designed to provide sun aspect angle and sun crossing pulses for spinning spacecraft. This information is used to determine spin rate and spin axis orientation relative to the sun.

Spinning Sun Sensor (±64°)

The ±64° Adcole Sun Sensor provides better accuracy and resolution than the MSSS. It is a redundant system consisting of one optical head per redundant electronics channel. It is used for attitude determination of spinning spacecraft, sun acquisition, and fail-safe recovery.
