摘要

混合激光/微波链路系统能够结合激光链路高速、低时延的优势和微波链路在恶劣环境下的稳定性，为卫星导航系统提供更可靠、高效的通信服务。以搭载混合激光/微波链路的导航星座为研究对象，对其导航星座的拓扑与路由展开研究，构建由Walker-δ 24/3/1 中地球轨道星座与地球静止轨道、倾斜地球同步轨道卫星组成的混合星座模型，分析星间链路体制特性。针对链路拓扑设计，提出激光链路环状与跨环连接方案，并使用模拟退火算法优化微波链路，进一步提高定位精度因子；在此基础上，提出一种基于图论匹配的测量时隙分配策略与通信时隙路由算法，并通过仿真验证其有效性。

Abstract

Hybrid laser/microwave links system can combine the advantages of high speed and low latency of laser links and the stability of microwave links in harsh environments to provide more reliable and efficient communication services for satellite navigation systems. Taking the navigation constellation equipped with hybrid laser/microwave links as the research object

and study the topology and routing of its navigation constellation. A hybrid constellation model based on Walker-δ 24/3/1 MEO constellation and GEO、IGSO satellites is constructed to analyse the characteristics of the inter-satellite link system. For the link topology design

a laser link ring and cross-ring connection scheme is proposed

and the microwave link is optimised using a simulated annealing algorithm to further improve the position accuracy factor. On this bais

a measurement time slot allocation strategy and communication time slot routing algorithm based on graph theory matching are proposed

and their effectiveness is verified by simulation.
