随着成像卫星硬件水平的提高,其应用目标也有了更高的要求。因为复杂的约束、难以预测的状态信息以及繁杂的需求种类,卫星任务规划问题一直是系统工程领域的难点问题之一。为更好地适应新的应用环境并满足不同用户的需求,设计了自主卫星任务规划系统。其包括星上与地面两个子系统,各子系统中均包含若干模块,分别实现不同的功能并协同完成某些复杂任务。基于对需求分析,整理出了卫星的应用场景、主要模块和关键技术。通过对两套系统的仿真结果比较,论证了该系统框架的可行性与优化效率,并为未来卫星任务规划系统的设计提供了思路。
With the improvement of the imaging satellite hardware level, its application target also has higher requirements. Due to complicated constraints, unpredictable state information and complicated types of requirements, satellite mission planning has always been one of the most difficult problems in the field of system engineering. To better adapt to the new application environment and meet the needs of different users, autonomous satellite mission planning system was designed. It includes two sub-systems of satellite and ground. Each sub-system contains several modules, which realize different functions and accomplish some complicated tasks in coordination. Based on the demand analysis, sorted out the satellite application scenarios, the main modules and key technologies. By comparing the simulation results of the two systems, the feasibility of the system framework and the optimization efficiency are demonstrated, and the ideas of the future satellite mission planning system are provided.
