Optical system design for micro star sensor

Star sensor is an important part of the attitude control of a space vehicle. The advantages and disadvantages of the optical system determine the accuracy of the whole star sensor system. In order to adapt to the development of China's space needs, a star sensor optical system was designed by a domestic CMOS sensor, domestic FPGA and domestic CPU. Its focal length F/#=1:1.73, f=43.56mm, working wavelength range: 400nm~780nm, field of view angle: 20 degrees × 20 degrees. Meet the requirements of the optical system of star sensor, and also meet the relevant technical indicators of the star sensor national standard 30111-2013 GB/T.
