Abstract

This paper depicts the general analysis before designing optics for an APS based star sensor. The high accuracy requirement and low sensitivity of APS make the optics overcritical. To avoid the extreme difficulty in optics, we abstract the PSF models in sub-pixel scale as the compensation for the distortion error. Both centroid and correlation algorithm are used to determine the spot center. The result of the simulation is presented in the text.
