一、回顾空间光学姿态敏感器主要指太阳敏感器、红外地平敏感器和星敏感器。该三种空间光学敏感器分别以太阳、地球和恒星为基准,对飞行器进行实时姿态(俯仰、滚动、偏航)捕获与测量,或修正陀螺平台系统,或经过信息处理直接进行姿态控制。其中,太阳敏感器还可用作红外地平敏感器和星敏感器的视场监视和保护,以及太阳帆板控制等。这三种光学敏感器的测量精度受其参考基准所限,以星敏感器为最高(秒级),太阳敏感器次之(一般大视场时为几分,小视场时可以
First, the review of space optical attitude sensor mainly refers to the sun sensor, infrared sensor and the star-sensitive surface. The three space optical sensors capture and measure real-time attitude (pitch, roll, yaw) of the aircraft based on the sun, the earth and the stellar respectively, or correct the gyroscope platform system or perform attitude control directly through information processing. Among them, the sun sensor can also be used as infrared land-level sensors and star-sensitive field of view monitoring and protection, and solar panel control. The precision of these three kinds of optical sensors is limited by their reference standards, the highest is the star sensor (second level), the second is the sun sensor
