摘　　要：随着遥感卫星对各类应用的支撑保障不断深入,卫星任务规划系统面临的外部环境复杂多变,如卫星轨道调整、在轨突发故障、任务随机到达、成像条件变化等,应急突发事件发生的随机性大大提高,传统的定期集中式任务规划架构逐渐无法满足高时效、高响应要求。通过分析系统外部环境种类及变化规律,设计分段分策略调度的任务规划架构,以及相应的调度策略和对象状态管理机制,实现对应急突发事件的高效响应能力。并在某遥感卫星任务管控系统项目中采用该技术架构并研制相应软件。系统实际运行结果表明,该分段分策略的任务规划技术架构基本上满足了外部环境动态变化引起的高适应和高响应要求,极大提升了系统的自动化程度和时效性指标。With the deepening of the support of remote sensing satellites for all kinds of applications,the external environment faced by satellite mission planning system is complex and changeable,such as satellite orbit adjustment,sudden failure in orbit,random arrival of tasks,changes in imaging conditions,etc.,and the randomness of emergency events is greatly improved.The traditional periodic cen-tralized mission planning framework is gradually unable to meet the requirements of high timeliness and high response.By analyzed the types and changing rules of the external environment of the system,the task planning framework of segmented sub-strategy adjustment was designed,as well as the corresponding scheduling strategy and object state management mechanism,and the efficient response abil-ity to emergency emergencies was realized.The technical framework was adopted in a remote satellite mission management and control system project and the corresponding software was developed.The actual operation results of the system showed that the technical framework of mission planning with segmented strategy proposed in this paper basically met the requirements of high adaptability and high response caused by dynamic changes of external environment,and greatly improved the automation degree and timeliness index of the system.
