【摘要】 太阳电池阵是航天器电源系统的重要组成部分,通过光生伏特效应将太阳光能转换为电能,满足卫星平台及有效载荷功率需求,同时为蓄电池充电,满足阴影期卫星功率需求。收集、整理了基于地球同步轨道(以下简称GEO轨道)运行的太阳电池阵的在轨遥测数据,并与地面测试和预计数据进行了比对,分析了预计结果与遥测值的符合性;同时还获得了应用于该平台的砷化镓太阳电池阵的在轨温度及进出影温度变化情况,并初步摸索出了太阳电池阵在GEO轨道辐照条件下的初期性能变化趋势。更多还原

【Abstract】 Solar array is an important part of the electrical power subsystem(EPS) of the spacecraft,which converts sunlight into electrical energy to provide primary power for the satellite.It is designed to satisfy all electrical power requirements of satellite during sunlight portions of the orbit,including satellite housekeeping,payload operations,and battery charging.The remote sensing data of GaAs solar array was collected and sorted in this paper,which was compared with the ground testing data and anticipate data.According to all of the data analysis,the coincidence between anticipate result and remote sensing data was obtained,as well as temperature variety of GaAs solar array in orbit,performance variety trend of the solar array in GEO.更多还原
