摘要 | Space astronomical telescopes must test the image stabilization accuracy of their image stabilization system prior to entering the orbit. According to the position characteristics of the fine guidance sensor of telescopes required by the China National Space Administration, a simulation model of moving guide stars is proposed in this study to test the image stabilization accuracy of space telescopes. The simulation model for synchronous moving guide stars is based on the principle of mutual collimation of the diagonal field of view of the optical system of telescope. Realize the multi-field moving guide stars with high synchronization accuracy simulated by the same target source. Compared to traditional methods, this method requires simple manufacturing and has high flexibility. The error sources affecting the simulation accuracy of the moving guide stars are analyzed, and an error model is established. Analysis results show that the simulation accuracy of the moving guide stars can reach 0.046 ''. The simulation model of guide stars is verified through experiments in which the influence of the vibration isolation platform is considered. Experiment results show that the simulation accuracy of motion guide stars is 0.036 '', satisfying the accuracy requirements (<0.0800) of the accuracy test for the telescope image stabilization of telescopes.
