Small satellites are capable of performing space explore missions that require accurate attitude determination and control. However  low weight  size  power and cost requirements limit the types of attitude sensor of small craft  such as CCD  are not practical for small satellites. CMOS APS is a good substitute for attitude sensors of small craft. Some of the technical advantages of CMOS APS are no blooming  single power  low power consumption  small size and little support circuitry  direct digital output  simple to system design  in particular  radiation-hard characteristic compare with CCD. This paper discusses the application probability of CMOS APS in star tracker for small satellites  further more  a prototype ground-based star camera based on STAR250 CMOS image sensor has been built. In order to extract stars positions coordinates  subpixel accuracy centroiding algorithm has been developed and tested on some ground-based images. Moreover  the camera system star sensitivity and noise model are analyzed  and the system accuracy is been evaluated. Experimental results indicate that a star camera based on CMOS APS is a viable practical attitude sensor appropriate for space small satellites.
