The Redwire Fine Spinning Sun Sensor± 64° provides better accuracy and resolution than the Miniature Spinning Sun Sensor. The unit is Rad hard to 100 krad (Si).

Redwire 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.

This redundant system consists of one optical head per redundant electronics channel. It is used for attitude determination of spinning spacecraft, sun acquisition, and fail-safe recovery.
