卫星的小型化发展趋势相应地要求姿态敏感器件必须小型化。该文介绍了一种采用光学非线性补偿方法的两轴微型太阳敏感器技术。该敏感器在两个轴上的测量范围可以同时达到120°(±60°),测量精度优于0.1°,而其外结构尺寸只有50mm×50mm×25mm,总质量只有78g,总功耗小于24mW。其体积小、质量小、功耗低等特点可以满足微小卫星等航天系统对姿态测量敏感器部件的要求。该文给出了这种微型太阳敏感器的理论工作原理与实验测试结果。
The miniaturization trend of satellites accordingly requires that attitude-sensitive devices must be miniaturized. This paper presents a two-axis miniature solar sensor technology using optical nonlinear compensation. The measuring range of the sensor can reach 120 ° (± 60 °) at the same time in both axes, the measuring precision is better than 0.1 °, while the external structure size is only 50mm × 50mm × 25mm, the total mass is only 78g, the total power consumption is less than 24mW. Its small size, low mass, low power consumption and other characteristics to meet the micro-satellites and other space systems on the attitude measurement sensor components requirements. This paper gives the theoretical working principle and experimental test results of this miniature solar sensor.
