Abstract: A motion compensation (MC) method is introduced to improve dynamic capability of star tracker. Then the MC principle is explained in detail, including charge-transfer in hardware and SNR-improving in software, with the emphasis on implementation means and conditions. The charge-transfer in hardware include special disposal in X and Y directions of charge couple device (CCD)，and SNR-improving in software is realized in digital signal processing (DSP) .Finally, in order to improve the dynamic capability, primary design and calculation based on STS star tracker made in China are presented. The results show the MC takes effect on dynamic capability improvement of star sensors.
