面向新型成像卫星自主任务规划系统设计

Autonomous mission planning system design for novel imaging satellite

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 hardware on imaging satellite, the application targets also have higher demands. Because of the complex constraints, unpredictable state information and diverse requirement types, satellite mission planning has been one of the difficult problems in the field of system engineering. In or- der to adapt to new environments better and meet the needs of different users, the autonomous satellite mission planning system is presented. It includes two subsystems-the satellite subsystem and the ground system, and each of them contains several modules, respectively, to achieve different functions and complete certain complex tasks as a whole. Based on the needs analysis, the satellite＇s application scenarios, the main module and key technologies are sorted out. Through the comparison of the simulation results of the two systems, the results show the feasibility and efficiency of optimization of the new system framework, and provide a guideline for the design of future satellite mission planning system.
