Miniature Spinning Sun Sensor (±87.5°)

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, Themis, and MMS satellite clusters.
