PROBLEM TO BE SOLVED: To inexpensively provide a star sensor system by reducing signal lines and interface parts for connecting each sensor and a sanitary control device to the minimum. SOLUTION: The star sensor system is provided with a plurality of optical systems condensing light from a fixed star, a star sensor having a plurality of light receiving elements for detecting the azimuth of the fixed star by receiving light condensed by the optical systems, and a plurality of solar sensors mounted on a body fixing the star sensor or on a baffle shielding all light except one from a specific visual field and measuring the intensity of sunlight.
