摘　　要：太阳探头响应的能量是太阳可见光辐射.在卫星轨道,地球大气和表面产生的反射光照也能进入太阳探头的视场.针对风云一号C星和风云三号气象卫星,综合考虑了卫星发射的窗口、轨道、大气漫反射和太阳直射等因素,从理论上分析和推算了太阳探头响应地表及大气反照的各种结果,并作为风云一号C星姿控系统复核复算的依据,也可为风云三号卫星姿控系统提供参考.The sensitive energy of sun sensor is visible light＇s radiate from sun. In the satellite orbit, the radiation from earth＇s atmosphere and surface can also come into the sun sensor＇s field of vision. Based on the FengYun No. 1 C and No. 3 weather satellite, various influences of earth radiation on sun sensor were theoretically analysed and calculated after considering the factors of satellite＇s launching time and orbit, as well as atmosphere diffuse reflection and sun＇s irradiation. The research result is the foundation of FengYun No. 1 C satellitic gesture controlling system check, and it can also provide reference to FengYun No. 3 satellite.
