Miniature Spinning Sun Sensor (±87.5°)

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.
  • The Miniature Spinning Sun Sensor is designed for use on small spinning satellites. This sensor has flown on the ST5, Themis, and MMS satellite clusters.
  • The MSSS is Rad Tolerant, or Rad hard to 100 krad (Si).
