摘　　要：为了减少地面人工操作失误带来影响,增加卫星在轨任务执行成功率,本文对太阳同步近圆轨道卫星星上自主任务规划进行了探讨,提出了一种根据轨道系太阳矢量规划载荷任务的方法.利用轨道系太阳矢量,推导卫星与太阳的相对位置和角度变化,计算出卫星载荷任务的起止时刻等关键点,进而控制星上单机进行任务观测.结果表明,该方法可显著减少卫星执行任务时所需要地面上注的指令条数,减少由于地面上注时延带来的观测误差,本文所提方法可为相关卫星自主任务规划提供工程借鉴,为未来提供星上在轨智能决策提供理论参考.In order to increase the success rate of satellite in orbit mission execution and reduce the impact of manual operation errors,discussing on-board autonomous mission planning of solar synchronous near circular orbit satellite,a method was proposed for load mission planning according to the solar vector of the orbit system.Using solar vector of the orbit system,the method was designed to derive the relative position and angle change between the satellite and the sun,to calculate some key points such as the start and end time of the satellite load mission,and then to control single machine on the satellite for mission observation.The results show that this method can significantly reduce the number of needed instructions from ground during satellite executes the mission,and reduce the observation error resulted from injection time delay of the ground.The method proposed in this paper can provide engineering reference for related satellite autonomous mission planning,and provide theoretical reference for on orbit intelligent decision-making in the future.
