Abstract: To solve the defects and deficiencies of current algorithms with less generality and incomplete constraints,the software architecture of mission planning was designed with 7 sorting strategies,8 time window selection strategies and 8 sub-function components.By using time window clipping algorithm,different kinds of time window overlap were considered to avoid conflicts and ensure the back-operation activities after observation.Such component-based modular heuristic methods could achieve autonomous mission planning system in the future.

摘要： 为解决目前成像卫星系统任务规划算法通用化差、考虑约束不全面等缺陷,设计并实现了具有7种排序策略、8种观测与回传时间窗选择策略和8个分功能组件的任务规划软件架构。该方案采用时间窗裁剪算法,分类考虑不同时间窗重叠的情形,以避免冲突且确保回传在观测之后发生,这种组件式、模块化的启发式方法为下一步实现自主任务规划系统打下了基础。
