  • This paper presents the working principle of dynamic star simulator and the calculation of star position error. According to the working principle, a star position correction method was derived based on distortion of star simulator optical system. The correction model is established and the correction formula is deduced through correction principle. By analyzing the optical system, the fitting curve between field of optical system and correction value of star position can be attained with Matlab. After selecting the revise range by means of ascertaining the critical value of field, and revising the star position on display device using the correction formula, the original requirements were met. The proposed correction can lower the requirements of optical system designing and provide an effective method for star position correction of dynamic star simulator.
