Digital Sun Sensor (±64°)

Adcole Two-Axis Fine Sun Sensors are used for attitude determination, sun acquisition, solar-array pointing and fail-safe recovery. Many systems have flown with 1 to 8 sensor heads per processing electronics.

Digital Sun Sensors
Number of Measurement Axes 2 (each sensor)
 Number of Sensors 5 typical per electronics. 1 to 8 sensors can also be used. Electronics selects the sensor with highest sun intensity. Sensor selection via spacecraft command is also available.

Note: 4π steradians (full sphere) coverage can be achieved with 5 sensors.

Field of View 128° x 128° (each sensor)
Accuracy ±0.25° (transition accuracy)
LSB Size 0.5°
