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.
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.
