摘要

摘要:
针对大规模卫星星座开展通信资源的研究，随着多个低轨星座的成功构建，标志着大规模卫星星座的商用化已经开始。这类大规模卫星星座可以同时兼顾低时延、广覆盖和大流量的优点。高效利用地面站资源成为大规模卫星星座研究的技术瓶颈，针对该问题，提出多星及多站拓扑结构，并结合链路时间资源，提出星地链路时间模型。同时，提出时隙插入策略，以多地面站的整体链路效能作为优化目标，得到多星及多站链路时间表。通过与随机策略和贪婪策略的性能对比，验证了所提策略的可行性和优越性。

Abstract:
Aiming at the research of large-scale satellite constellation, the research content of communication resources is put forward. With the successful construction of several low-orbit constellations, the commercialization of large-scale satellite constellations has begun. This kind of large-scale satellite constellation can simultaneously take into account the advantages of low delay, wide coverage and large traffic. In order to make efficient use of earth station resources, it has become the technical bottleneck of large-scale satellite constellation research. The multi-star and multi-station topology is proposed to better focus on this problem. Combined with the link time resources, a satellite-earth link time model is proposed. On this basis, the time-slot insertion strategy is proposed, and the multi-star and multi-station link schedules are obtained by taking the overall link efficiency of multi-ground stations as the optimization objective. The feasibility and superiority of the proposed strategy are verified by comparing the performance with random strategy and greedy strategy.
