Summary

The Redwire Miniature Spinning Sun Sensor (MSSS) is designed to provide sun aspect angle and sun crossing pulses for spinning spacecraft. This sensor has flown on the ST5, Themis, and MMS satellite clusters.

The information provided by the MSSS is used to determine spin rate and spin axis orientation relative to the sun. The MSSS is delivered as a fully integrated unit with optical heads and electronics processing circuitry. The MSSS is radiation tolerant, or Rad hard to 100 krad (Si).

Sun Sensors are export controlled through an ECCN (Export Control Classification Number) issued by the United States Department of Commerce, ECCN 7A104. Export shipment requires successful application for an export license.
