The star sensor is a high-precision attitude sensitive measuring instruments, which determine spacecraft attitude by detecting different positions on the celestial sphere. Star camera is the imaging system of star sensor. Despite the rapid development of CMOS technology, in science class imaging, especially, CCD camera still has a great advantage in applications of star sensor. The purpose of this study is to increase the performance and data update frequency of CCD camera for star sensor. The working principle of CCD is described, the CCD sensor detection sensitivity is analyzed, and the design of CCD star camera is discussed based on TH7888A. Performance of the camera can be validated through imaging and detection experiments. By analyzing the experimental images, it is found that the camera can detect Mv6 stars in 60 ms integration time through a given the small optical system. The camera’s image data update frequency can reach 10 frame/s and meets the rapid imaging requirements in short integration time.
