该文根据卫星自主导航技术研究的需要,设计了基于HLA的仿真系统。在分析卫星自主导航技术基本原理的基础上规划设计了系统的仿真场景,根据任务功能需求提出了基于高层体系结构的卫星自主导航仿真系统框架,在对仿真系统中的卫星成员、恒星成员和控制成员等主要联邦成员的行为进行建模后,详细设计了相应的成员类,并对整个仿真系统的时间推进机制和时间管理策略进行了设计和说明。根据上述设计方案构建的仿真系统,可以对卫星自主导航技术进行仿真试验,从而完成其体制演示和关健技术验证。

In this paper, a simulation based on HLA is designed for the research of satellite autonomous navigation technology. According to the basic theory of this field, the simulated scene of simulation is schemed. After the analysis of required functions, a framework of HLA - based simulation for satellite autonomous navigation is presented. Then the action of satellite, star, and controller which are primary federates in the simulation is modeled. Followed that, corresponding classes of these federates are designed. At last, the time advancing rule and management policy in this simulation are designed and illuminated. Through the test platform provided by the simulation based on the resolution described above, the demonstration and critical technology verification of satellite autonomous navigation can be implemented.
