摘　　要：随着卫星技术和通信技术的发展,传统的卫星星座网络正逐渐被由大量微纳卫星组成的分布式星群网络所替代,但随之带来了星群网络内部组网机制自组织、自适应方面的问题。由此,根据星群组网的具体场景提出了一种分布式星群网络(Distributed Satellite Cluster Network,DSCN)体系架构,给出了通信网络中的物理层、数据链路层、网络层的设计方案。同时,针对典型应用场景,结合编队构型的仿真,开展星间通信的物理层、链路层和网络层的通信网络仿真演示验证,并以此搭建硬件演示验证平台,为微纳星群的在轨应用提供信息通信保障。With the development of satellite technology and communication technology,the traditional satellite constellation network is gradually being replaced by a distributed constellation network composed of a large number of micro-nano satellites.However,it also brings about self-organization and self-adaptation problems in the internal networking mechanism of the constellation network.Therefore,this paper proposes DSCN(Distributed Satellite Cluster Network)architecture based on the specific scenarios of the satellite cluster network,and presents the design scheme of the physical layer,data link layer,and network layer in the communication network.At the same time,for typical application scenarios,combined with the simulation of the formation configuration,the communication network simulation demonstration and verification of the physical layer,the link layer and the network layer of the inter-satellite communication are carried out,and a hardware demonstration and verification platform is built on this basis.This provides information and communication guarantee for the on-orbit applications of the micro-nano constellation.
