Walker星座卫星网络拓扑结构动态性分析

Topological dynamics analysis of Walker-constellation satellite networks

对低轨道(LEO)、Walker星座类型的卫星网络拓扑结构动态变化特征进行量化,给出了精确计算系统周期内网络时间片数量和时间片长度的公式。通过研究,一方面弥补了卫星网络研究中对拓扑结构时间片特征的简单假设,另一方面也为未来卫星网络星座的设计提供一定的指导。

The dynamical activates of low earth orbit （LEO） Walker constellation satellite network topologies was quantified. The number and length of network snapshots were formulated concisely. It compensates for the simplified topological assumptions in many LEO satellite network related investigations. The thorough understanding of this basic feature not only provides for an accurate quantification of network behavior, but also guides future constellation design for satellite networks.
