About

The Adcole Space Fine Spinning Sun Sensor (±64°) provides better accuracy and resolution than the Miniature Spinning Sun Sensor, making it the preferred choice for spinning spacecraft that require more precise attitude determination. The sensor features a redundant architecture, with one optical head paired to each electronics channel, providing graceful degradation and fail-safe operation.

Designed for spinning spacecraft attitude determination, the Fine Spinning Sun Sensor supports sun acquisition operations and fail-safe recovery in addition to normal attitude determination. The redundant configuration with paired optical heads and electronics channels ensures continued operation if one channel fails, critical for long-duration missions.

The sensor covers a ±64° field of view — sufficient to capture the sun across the full range of spin axis orientations encountered in typical spin-stabilized satellite operations. At 0.71 kg and 0.4 W average power, it is compact and power-efficient while delivering higher accuracy than the miniature variant.
