| Abstract: | 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. |
