【摘要】 星模拟器是为了模拟星象点的星等值、大小和光谱特性的光学仪器,从而实现对星敏感器探测能力和空间分辨率等的地面定标。在航空航天事业、卫星、飞船以及太空空间站等的研究中均具有很深远的意义。本论文首先介绍了星敏感器国内外的发展概况,对星模拟器的原理进行了详细的介绍。其次,为改善以前体积过大、精度不高、长期稳定性不够等缺点,结合技术指标要求,用数字式光源的设计方法,利用闭环进行控制并采用大规模集成电路模块,既提高了精度同时还增加了稳定性。另外,还详细叙述了对星模拟器整个系统的研制方法和技术,以及光学系统的设计和调试,并对系统误差进行分析。更多还原

【Abstract】 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.更多还原
