摘　　要：太阳敏感器作为检测太阳矢量方位角的一种光学仪器,是卫星进行姿态测量、确定和控制的重要敏感器.随着天基对日观测活动的发展,对日精确指向需求强烈,太阳敏感器的精度和数据更新率成为制约对日观测平台稳态控制和精确观测的关键因素.针对太阳敏感器高精度和高更新率的需求,从光学系统、电路系统和软件算法等多个角度出发,设计了一种太阳敏感器,经标定测试,精度随机误差达到0.716″(3σ),更新率达到62 Hz.As an optical instrument for detecting the azimuth of the sun vector,the sun sensor is an important sensor for satellite attitude measurement,determination and control.With the development of space-based solar observation activities,the demand for precise pointing to the sun is strong,and the accuracy and data update rate of sun sensors have become the key factors that restrict the steady-state control and accurate observation of solar observatory.Aiming at the requirements of high accuracy and high update rate,a kind of sun sensor is designed considering the perspectives of optical system,circuit system and software algorithm.The error reaches 0.716″(3σ)and the update rate reaches 62 Hz.
