Scientific paper
A two-dimensional fine Sun sensor using linear CCDs is described. The sensor has a wide rectangular field of view of 50 deg by 50 deg around its normal, with angular resolution of 0.025 deg. The sensor was developed as one of applications of CCDs to spacecraft and is to fly for the first time on ASTRO-C, an X-ray astronomy research satellite which also incorporates onboard a set of star trackers using area CCDs. Through the performance and environmental tests on the sensor unit, it was qualified to meet all the requirements. Development of a CCD Sun sensor with higher accuracy is mentioned.
