TWO-AXIS DIGITAL SUN SENSOR SYSTEM
CONFIGURATION
-NO OF MEASUREMENT AXES: (2 each sensor)
-NUMBER OF SENSORS: 5 typical per electronics. 1 to 8 sensors can also be used. Electronics selects sensor that has sun in field of view.
HERITAGE
Many systems flown with 1 to 8 sensor heads per processing electronics.
PARAMETERS
-FIELD OF VIEW: 128° x 128° (each sensor)
Note: 4π steradians (full sphere) coverage can be achieved with 5 sensors.
-ACCURACY: ±0.25° (transition accuracy).
-LSB SIZE: 0.5°
APPLICATIONS
-Attitude determination
-Sun Acquisition
-Solar-array pointing
-Fail-safe recovery
