摘　　要：高分三号(GF-3)装载有大型合成孔径雷达(SAR)天线及大型太阳翼,因此在其飞行程序设计中要重点考虑太阳翼和SAR天线的展开设计,以及它们的展开对卫星的扰动力矩和姿态的影响。通过分析显示:太阳翼展开对卫星姿态角和姿态角速度影响较大,为此对几种太阳翼展开未锁定的情况作出故障预案;通过分析SAR天线展开的动力学特性,以及SAR天线展开对卫星姿态的影响,进行相应设计,并为实现SAR天线展开可控,采取相应措施。GF-3卫星在轨验证结果表明:太阳翼和SAR天线展开结果良好,飞行程序设计合理有效。GF-3 satellite are equipped with large SAR （synthetic aperture radar）antennas and large solar wings,so the design of satellite flight program should focus on the deployment of the solar wings,especially the SAR antenna,and the influences of deployment on the whole satellite＇s disturbance torque and attitude.The analysis of the solar wing deployment shows that it has a great influence on the satellite attitude angle and attitude angular velocity.Therefore,several fai-lure plans have been prepared for solar wings unlocked happening.By analyzing the dynamic char-acteristics of SAR antenna deployment and SAR antenna deployment influences on the satellites attitude,the corresponding designs are made,and some measures are adopted to make antenna deployment controllable.GF-3 satellite on-orbit verification results show that the solar wings and SAR antenna deploy well,and the flight program design is reasonable and effective.
