摘　　要：多星组网、编队飞行是小卫星应用领域的发展趋势。与之相适应,卫星信息系统正从单星向多星网络化发展,形成一个具有优化拓扑结构、完善通信协议和管理调度机制的统一天基信息网络系统,以实现对协同工作的多星系统的飞行任务管理。文章针对星座系统信息网络的技术特点、拓扑结构设计、网络模型设计、协议设计和一体化设计方法进行了论述,并从工程角度出发,分析了设计过程中应着重解决的关键技术问题。Multi-satellite network and formation flying are the trends of satellite application. Correspondingly,the information system of satellite is being developed from single satellite mode to multi-satellite network mode. Unified space-based information network system with optimized architecture, perfect communication protocol, outstanding management and scheduling mechanism are used to realize the mission management of the cooperating multi-satellite system. This article mainly focuses on the technical characteristics, topology design, network model design, protocol design and unified design of satellite constellation system, and analyzes those critical technical problems which were encountered during design process with an engineering point of view.
