摘要:

针对目前“北斗”导航系统星间链路维护中频繁进行的时隙表、路由表等数据上注耗时较长的问题，利用星座各星上注数据一致的特点，提出了一种“北斗”导航星座数据上注的动态链路树路由方法。该方法能够显著降低整个星座数据上注过程的资源占用，并较大幅度地提高完成数据上注任务速度，缩短数据上注的时间。

Abstract:

In view of the poor timeliness of uplink injection data update operation in the current Beidou navigation satellite system intersatellite link constellation maintenance,a dynamic link tree routing method for Beidou satellite navigation constellation data injection is proposed based on the consistency of the data injection in each constellation.This method can significantly reduce the resource occupation of the whole constellation note data update process,and greatly improve the speed of completing the note data task.
