中文摘要

      传统的航天器运行管控方式严重依赖地面指控、人力成本耗费大且对任务响应时间长，难以满足深空探测远距离通信时延突出的任务特点，航天器的智能化水平亟待进一步提高。本文通过对航天器自主运行问题进行系统地分析，提出一种能够支持航天器自主运行的体系结构，面向自主系统软硬件结构、自主管理分系统运行流程等进行了设计。重点针对小行星探测任务，提出了航天器自主任务规划演示验证仿真系统设计方案，实现自主任务规划仿真，能够根据高级任务目标输出完整的指令序列、各分系统或部件的动作时间线、以及相应的资源状态时间线，支持对相关算法和模型的可视化验证、分析等功能，为航天器自主运行技术研究提供了一种有益的思路和方法。

英文摘要

      The traditional spacecraft operation and control method relies heavily on ground accusation, the labor cost is large and the task response time is long, and it is difficult to meet the characteristics of the deep space exploration long-distance communication delay. The intelligent level of the spacecraft needs to be further improved. This paper systematically analyzes the autonomous operation of spacecraft, and proposes an architecture that can support the autonomous operation of the spacecraft. It is designed for the hardware and software structure of the autonomous system and the operation flow of the autonomous management subsystem. Focusing on the asteroid exploration mission, the spacecraft autonomous mission planning demonstration verification simulation system design scheme is proposed to realize the autonomous mission planning simulation. It can output the complete instruction sequence, the action timeline of each subsystem or component, and corresponding according to the advanced mission objectives. The resource status timeline supports the functions of visual verification and analysis of related algorithms and models, and provides a useful idea and method for spacecraft autonomous operation technology research.
