Sun Sensor Calibration for the Calibrated Orbiting Objects Project (COOP)

摘要

This Technical Note describes the calibration of the coarse and medium sun sensors for the Calibrate Orbiting Objects Project (COOP). The data presented will be used by the satellite contractor for Attitude Determination and Control (ADC). The coarse sensors were calibrated at 15 deg increments along orthogonal axes within its 120 deg field of view (FOV) and the medium sensors were calibrated at 10 deg increments along orthogonal axes within its 60 deg FOV. Step size was reduced to 2 deg increments between - 10 deg and +10 deg increase calibration resolution near maximum voltage output. Sensor performance as a function of temperature variance is also characterized for the expected operating range (5C to 69C).
