Research on Topology Management and Routing for Navigation Constellations with Hybrid Laser/Microwave Links
摘要
Abstract
Hybrid laser/microwave links system can combine the advantages of high speed and low latency of laser links and the stabil-ity of microwave links in harsh environments to provide more reliable and efficient communication services for satellite navigation sys-tems.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 satel-lites 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 im-prove the position accuracy factor.On this bais,a measurement time slot allocation strategy and communication time slot routing algo-rithm based on graph theory matching are proposed,and their effectiveness is verified by simulation.关键词
