摘　　要：月球是低轨气象卫星载荷进行外定标的一个理想目标,不同载荷通过观测月球可以建立统一的参考基准,提高相互之间的数据匹配性。对于低轨卫星,月球一般每月一次进入载荷的视场,但停留时间只有几秒钟。为进一步提高对月定标的观测时长,积累更多的观测数据,本文针对低轨偏置动量卫星提出了一种主动对月定标控制方案,通过卫星平台的姿态控制,使月球在载荷视场中停留30 min以上。仿真结果表明:对月定标过程中卫星姿态控制精度满足指标要求,具备工程应用条件。The moon is an ideal target for external calibration of low earth orbit(LEO)meteorological satellite payloads.With sharing the moon as a calibration target,different satellites can build a unified reference datum,which benefits for the data assimilation.Typically,the moon can enter the payload narrow scan window for only a few seconds once a month.In order to further improve the observation time for lunar calibration and accelerate more observation data,in this paper,an active lunar calibration control scheme for LEO biased momentum satellites is presented.The results show that with the presented scheme,the moon could stay in the payload window for more than30 minutes through the attitude control of the satellite platform.The simulation results indicate that the precision of satellite attitude control in the process of lunar calibration meets the requirements of indexes and engineering application.
