In this method, the precision orbit information of space target can be used to invert and calculate the characteristics of high-precision measurement elements, and the measurement equation is established to calculate the photoelectric deviation in combination with the measurement data of shipborne measuring equipment. The calculated results are taken as the theoretical values to optimize the photoelectric deviation obtained by many methods. The measured data show that the problem that the difference of direct calibration results is difficult to choose under dynamic measurement can be effectively solved.
