Paper Abstract

Star simulator is necessary equipment for calibration and performance testing of star sensor in laboratory. A novel method for adjustment of star simulator has been proposed in this paper. This method is based on ordinary Penta prism, guide rail, Charge Coupled Devices (CCD) camera and sub-pixel centroid algorithm. The CCD camera is used to image the star light replicated by the Penta prism instead of the autocollimator compared with the traditional adjustment of collimator. The analysis shows that the limiting parallelism error of the single star simulator is less than 0.49" after adjustment using this proposed method. It can satisfy the high accuracy adjustment of single star simulator.
