Spinning Sun Sensors

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.

The Adcole Miniature Spinning Sun Sensor is designed for use on small spinning satellites. This sensor has flown on the ST5 and Themis satellite clusters, and has been delivered for the NASA MMS program.

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.
