基于分布式星群的空间信息网络体系架构与关键技术

摘要

提出分布式星群网络的概念，即利用共轨控制、组网协同技术，整合空间邻近且独立分布的卫星资源，在同步轨道上将多颗小卫星整合等效为一颗大卫星，实现服务能力的增强。并提出基于分布式星群的空间信息网络体系架构，通过多星共轨、星间高速互联、分布式自主协同、资源虚拟化等关键技术，可以实现空间系统服务能力增强，多星合成覆盖，在轨智能自愈，为构建未来稳定可靠的空间信息网络提供借鉴。%In this paper, the concept of distributed satel ite cluster is proposed, which combines the“smal”geostationary orbit (GEO) satel ites into a“big”satel ite to enhance the capability of service by utilizing in-orbit control and networking cooperation. And the system architecture of space information network based on distributed satel ite clusters is proposed. Through the technologies of putting multiple satel ites at the same orbit, high speed interconnect between satel ites, distributed independent coordination and resource virtualization, the capacity of space system services is also enhanced, combined service through multi-satel ites, on-orbit intel igent self-restoring can be achieved. An option of building a reliable space information network in the future is provided.
