摘    要:针对新一代导航星座网络建设需求,提出了一种具有抗毁性的导航星座网络管理策略。一方面基于快照周期和逻辑位置概念分析了网络的动态拓扑结构,给出了星座网络分群管理模式,特别设计了群管理者以及群首的备份选择机制;另一方面对星座中MEO星层的通信链路进行冗余设计,给出了失效链路的重构方案。最后使用STK建立仿真模型对该网络管理策略的有效性进行了演示与验证。

关 键 词:导航星座网络  快照周期  逻辑位置  分群管理  抗毁

Abstract:A destruction-resistant management policy is proposed according to the requirement of construction in new generation navigation constellation network.On the one hand,dynamic topological structure of navigation constellation network is analyzed and group management mode especially the design of backup/replacement mechanism of group managers and headers is provided based on the concept of snapshot period and logical location.On the other hand, the scheme of link redundancy and link rebuild in MEO layer is given.Finally,the effectiveness of the policy is testified by simulation of STK.
Keywords:navigation constellation network  snapshot period  logical location  group management  destruction-resistant
