  • In order to realize the testing and calibrating of star sensor spectral detection capability, a set of ground calibration system which can simulate the stellar spectra is developed, and the stellar simulation accuracy is required to be better than 10%. Spectral distribution controllable and light intensity adjustable light simulation system is adopted to be the core device to simulate changes in stellar spectra, collimating optical system with high image quality is designed to make the star map exit parallel light and present the star map at the exit pupil of optical system, then the high accuracy star map simulation with stellar spectra information is completed. Finally, using Lighttools, the spectral simulation model of calibration system is established and simulation results show that the stellar spectra simulation accuracy is better than 10%.
