合成观测可以提高卫星的观测效率,研究了遥感卫星的动态合成观测调度问题。分析了卫星对多个任务合成观测的条件,在此基础上,建立了任务需求度、资源竞争度以及任务合成中的最小侧摆、最小数据冗余启发式,提出了基于动态任务合成的多星观测调度启发式算法。仿真实例表明,此方法可以有效提高卫星的观测效率。
When multiple spot targets are located in same swath, they can be merged and observed within one observing activity. Task merging can improve satellites' observing efficiency. For this propose, a heuristic algorithm for multiple satellites observing scheduling with task merging was proposed. The algorithm contains many criteria, such as: the priority, the number of opportunities, resource contention and resource consumption for task merging. Experiments results show the effectiveness of the approach.
