| The star simulator is a testing equipment to simulate Stellar Magnitude, size, and spectral characteristics of a star, in this way the functional testing for the detecting and interspatial distinguish ability of a star sensor can be carried out and the simulated star can be given at real. It is very meaningful for the study of aerospace career, satellite and space station.At first, this paper introduces the development of domestic and international star sensors, expounds principle of the Star simulator. Secondly, Aimed at getting rid of big bulk, low precision, limited stability of the star simulator, while combining with the technical specifications of star sensor, the paper proposes to use high stability adjusted digital light source as the core elements, which is used the closed-loop control and large-scale integrated circuit module, not only improves the precision but also increase the stability of the Star simulator. Additional, this paper describe the development of the whole system star simulator method and technique in detail, design the optical system and analyze the systematic error. |
