Problems solved by technology

However, the problem brought about by the decoupling topology of the constellation network and the ground network is that it is difficult to determine the destination node of the reverse link (from the user to the gateway station). The service area division of gateway stations and the relay switching of satellite feeder links between adjacent gateway stations, if only considering the topology changes of the satellite constellation network, cannot truly reflect the entire network topology (inter-satellite and satellite-ground) structure and the actual connectivity status of the link

Abstract

The invention relates to the technical field of low-orbit satellites, in particular to a low-orbit communication satellite constellation inter-satellite route selection method and device. Through themethod, the constellation network only needs to call the routing table according to time fragments, so that the workload of a ground operation control system is effectively reduced, through fine division of time slices, optimized routing can be obtained, time slices are divided at equal time intervals so that the requirement for satellite equipment performance is effectively lowered, meanwhile, frequent signaling interaction caused by high-speed movement of a satellite is avoided, and the routing decision process is simplified. By coupling processing on the constellation network and a ground network, the method fully considers the problems of feed link service area division and relay of the low-orbit constellation satellite among the gateway stations, has the advantages of low routing computation complexity, fast routing decision, low requirements on satellite equipment performance and the like, has obvious advantages in the aspects of adaptability and feasibility, and is very suitablefor the selection process of inter-satellite routing in the low-orbit satellite constellation.

Description

Technical field [0001] The invention relates to the technical field of routing strategies for low-orbit satellites, in particular to a method and device for routing between satellites in a low-orbit communication satellite constellation. Background technique [0002] With the rapid development of Internet applications, the demand for Internet access services has increased dramatically. Compared with the traditional terrestrial communication system, the low-orbit satellite constellation communication system has the advantages of wide coverage, less influence by topography and strong anti-destroy ability. The current low-orbit satellite constellation communication system is divided into satellite communication constellations with inter-satellite links and communication satellite constellations without inter-satellite links according to whether the satellites have routing capabilities. For a low-orbit satellite constellation system without inter-satellite links, in order to enable ...
