About
The ACSS (Advanced Coarse Sun Sensor) is a wide-angle analog sun sensor designed for satellite constellations requiring robust attitude acquisition capability. It provides redundant coarse sun vector measurement with wide field of view coverage suitable for initial acquisition, safe mode operations, and attitude determination in tumbling recovery scenarios. The analog output voltage varies with incident angle, requiring simple A/D conversion in the satellite OBC. The ACSS is optimized for constellation deployments where cost per unit and ease of integration are critical factors.
