摘要
星间链路技术降低了卫星通信网络对地面站的依赖,使得基于星间链路的卫星通信与组网具有地面网络难以比拟的优势。传统研究集中于星间链路的可行性分析和构建方法,对星间链路方案设计缺乏评价。从实际应用的系统性和构建流程的完整性出发,提出一种基于星座特性分析的星间链路方案设计方法,并为方案性能检验和选择提出了基于路由性能的评价方法。最后,通过对实际系统星间链路方案的设计和评价,验证了所提方法能够针对任务需求构建可行方案并通过路由性能比较选出最优方案。
The inter-satellite link（ISL）technology reduces the dependence of satellite communication network on the ground station so that ISL-based satellite communication and networking show incomparable advantages over territorial network.Conventional studies focus on the feasibility analysis and construction method of the ISL in absence of design evaluation.Based on the systematic application of the system and the integrity of the process,this paper proposes an ISL design method based on the constellation analysis and presents a routing performance evaluation method for performance evaluation and selection of the schedule.In the end,through ISL plan design and evaluation,the paper draws a conclusion that the proposed method can be used to make a feasible scheme meeting task demand and select an optimal plan by routing performance comparison.
