| 摘 要： | 基于分群管理、群首备份、链路冗余、链路修补的二代导航卫星网络组网结构，提出并设计了一种基于GEO星层、MEO星层、地面节点联合组网的抗毁路由算法（DRRA）。基于二代导航动态卫星网络中卫星移动的动态卫星网络中，提出的DRRA算法在定位信号稳定、数据包路由抗毁、数据包路由最短延时等方面具有优势，并分析了其主要原因。

| Abstract: | A Destruction-Resistant Routing Method and Technique（DRRMT） of GEO/ MEO constellation is proposed in this paper, DRRMT with shortest delay path is based on the constellation architectures with grouping management, header of group backup, link re- dundancy, and link repair. DRRM has superiority in stable positioning signal, data packet route survivable and shortest time delay. The reasons are presented. |
