Research on ground testing for star sensor

The starlight navigation is considered to be one of the most important methods for spacecraft navigation. Starlight simulator system is a high-precision system with large fields of view, designed to test the starlight navigation sensor performance on the ground. A complete simulation of the system has been built. The starlight sensor testing system consists of star simulator, star scene generation computer, sensor control computer. The starlight simulator is made up of power module, light source, LCD, display circuitry, optical collimator and computer interface. LCD and optical collimator are the key display component of starlight simulator.
