基于轮询建链的相控阵星间链路方案在星间观测等方面具有优势，同时也对信息传输的路径选择提出了挑战。针对轮询建链规则下网络拓扑频繁时变的问题，对信息传输的路径选择进行了研究。在 Walker24/3/2星座基础上假定了一种轮询建链规则，构建了相应的数学模型对信息传输过程进行描述，在假定规则和所提数学模型的基础上，提出了一种星座内信息传输路径选择方法，保证在不影响星间测距的前提下，解决了多个导航信息在任意卫星节点间并发传输时的路径选择计算问题。最后以单个信息和2个信息流的并发传输为例，通过 Matlab 仿真计算证明了方法的可行性，对全球导航系统星间链路的路由选择具有一定的参考价值。

The phased array inter-satellite links (ISLs)solutions based on polling chain-built have many advantages on the inter-satellite measurement.At the same time,it presents a challenge on path selection of information transmission.Aiming at the problem of frequent change of network to-pology under the rules of polling chain-built,we had a research on path selection of information trans-mission.In this paper,we assumed a rule of polling chain-built on the basis of Walker24/3/2 constel-lation and built a mathematic model to describe the process of information transmission.On the basis of the assumed rules and mathematics model,we solved the path selection problems of multiple pieces of navigation information which can be transmitted between any different satellites.Finally,we took the transmission of single or two pieces of information for the examples and proved the practicability of the method we presented with Matlab software.It has some reference values for the routing strate-gy selection of Global Navigation System.
