Abstract

Star sensor provides high precision coordinate and spatial orientation through taking stars as the frame of reference, which is a kind of high-precision attitude sensitive measuring instrument. It has the advantages of high precision, strong anti-interference capacity, autonomous working and so on. In this paper, it analyzed the advantages and disadvantages between CMOS and CCD, and then, it introduced the working principle of the star sensor. After that, it deduced the correlation between the non-uniformity index and the other key technical indexes of star sensor, such as SNR, field of view, focal length, detection capability and photoelectric conversion efficiency. Finally, it has made a simulation of the relationship between PRNU and SNR according to the certain CMOS detector and theoretical design parameters, which can provide the theoretical basis for the CMOS detector selection of star sensor.
