摘　　要：以中国下一代静止轨道气象卫星为对象,分析了有效载荷扫描镜运动和太阳翼步进运动对卫星姿态的影响。结果表明,有效载荷的正常扫描运动和太阳翼的步进运动对卫星姿态的影响很小,但有效载荷的黑体校准运动对卫星姿态的影响很大,必须进行补偿控制,否则卫星有效载荷扫描镜的指向精度无法满足设计要求。With the background of the next generation of geostationary orbit meteorological satellite , the effect of payload mirror motion and solar array stepping motion are studied. The simulation results show that the effects of payload mirror regular scanning motion and the solar array stepping motion on the satellite attitude are very small. But the satellite attitude is deeply affected by payload backbody calibration, so the compensation must be required, otherwise the pointing performance of payload mirrors can not meet the demands of satellite.
