摘要: 介绍星敏感器和星模拟器在航空器空间姿态确定中的作用和地位及其基本工作原理。依据色度学理论与公式，分析如何使用红、绿、蓝三原色合成各种颜色的光源，并推导三原色色品坐标和亮度与合成光源色品坐标之间的数学方程式。在理论研究的基础上，设计一种以全色彩RGB灯作为发光器件的静态多路星模拟器电控光源。在实验室条件下，对电控光源系统输出光功率和峰值波长的稳定性进行测试实验，并给出实验结果。实验结果表明：单个光源的短期稳定性均优于1/1 000。Abstract: The role and status of star sensor and simulator in the determination of spacecraft spatial attitude were researched, as well as the basic working principle. According to the colorimetry theory and formula, how to form various synthesis light source color with red-green-blue(RGB) color was analyzed, and the mathematical equation was deduced between the RGB color coordinates and brightness coordinates with a synthesized source chromaticity. On the basis of theoretical research, a kind of static multi-star simulator circle controlled light source which used full-color RGB lamp as the light emitting device was put forward. Under the condition of laboratory, the output light power and wavelength stability of the circle controlled light source system were tested in experiments, and the experimental results were given. The experimental results showed that the short-term stability of the light sources was always better than 1/1 000.
