  • The research and development of CCD circuit, including both hardware and software are introduced in this paper. This circuit will be employed in the Ultraviolet Sensor (UVS) system of CE1 satellite, which is one of Chinese projects of detecting the moon. UV CCD sensor is made of optical structures, CCD and its processing circuit, Data Process Unit (DPU) and its software. The light of incidence goes iuto CCD, reflected by ichnographic mirror and thrilling through lens, and is transformed to digital signal by video processing circuit. The digital image signal is stored in data memory, and is analyzed by DPU. The calculated moon center is transformed to the attitude angle of detector to moon finally. UVS CCD circuit system includes CCD circuit, timing circuit, driver circuit, video process circuit and power circuit. The key device (CCD) is CCD48-20 from E2V company. It is detailedly introduced about CCD's timing and driving, smear problem, and so on.
