Abstract
In order to develop accurate satellite position error correction algorithms and get the topography information of the surface contour of the star image, the method used to measure the PSF of star tracker is explored. The distribution of star image is got. The PSF is reconstructed with the extended Nijboer-Zernike theory. The experiment testifies that it is a precise way to get the Zernike coefficients when the SNR of the star image is low. The algorithm and equipment fulfill the requirement of ultra-high accurate star tracker measurement.
