In order to suppress the influence of ground environment disturbance and improve the calibration accuracy of the ground verification test of star sensors, a star simulation technology with the jitter compensation function is proposed. This technology uses a tunable laser as the light source to achieve a beacon light with jitter compensation. In addition, it employs a large-diameter beam-splitting prism to achieve a multi-target star map combination and a large-diameter high-precision piezoelectric deflecting mirror to give feedback on and compensate for starlight in real time. Furthermore, a long-focus collimator is utilized to provide stable stars for high-precision star sensors. The performance of the system is studied through simulation, and the results show that the compensation accuracy peak deviation is 0.045″, and the compensation resolution is 0.01″. Then, a star map simulation system based on the jitter compensation system is constructed, and the system is measured with a 4D interferometer. The results show that the compensation resolution of the system reaches 0.01″, with the compensation accuracy better than 0.1″. This technology can detect the slight deviation of the optical axis and perform high-precision compensation. It can also provide a stable star target for the ground verification system of the high-precision star sensor and offer a solution for subsequent systems that require a highly stable target source.
