摘　　要：为了提高导航星座的自主性,有必要研究导航系统的自主导航能力。基于HLA建立了分布式的导航星座自主导航仿真系统。介绍了系统的组成以及各部分之间的关系,详细描述了系统中主要部分的实现技术,提出了导航星座自主定轨以及自主守时的主要算法,并对算法进行了仿真验证。仿真系统运行稳定,能对各种导航星座自主导航能力进行评价。计算结果表明提出的自主定轨算法和自主守时算法能够满足导航星座自主导航的基本要求。In order to improve the independence of navigation satellite constellation, the research on its auto-navigation capability is necessary. Based on the HLA technology, the distributed auto-navigation simulation system for the navigation satellite constellation was established. The compositions of this system and their relationship were introduced. And the technologies implementing the main parts of the system were described. The algorithm of auto orbit determination and time determination were proposed and verified through simulation. The system runs stably, and can evaluate the auto-navigation capability of the navigation satellite constellation. Known from the computation results, the above two algorithms meet the basic requirements of the navigation satellite constellation.
