摘要
空间自组网技术的研究对提升航天器编队空间拓扑适应能力、星间链路可靠性和卫星网络故障容错能力具有重要的意义。随着航天任务对星群规模和多星协同能力的要求越来越高,科研工作者对航天器自组网技术进行了深入研究,并取得了显著成果。主要梳理了航天器组网任务的拓扑构型、链路特点、轨道构型,分析了航天器组网的特点与发展趋势。同时介绍了应用于航天器自组网领域的基于节点拓扑规划的时频同步测量技术、网络多域信息主动认知的组网路由技术、基于相控阵捷变波束指向的自组网通信技术等。最后,思考总结了一些开放性问题及其发展趋势,可为后续从事该方面的研究人员提供参考和借鉴。
The research on space ad hoc network technology is of great significance in improving the space topology adaptability of spacecraft formation,reliability of inter-satellite links and fault tolerance of satellite networks.As space missions are placing increasingly higher requirements for the scale of constellations and multi-star coordination capabilities,scientific researchers have conducted in-depth research on the spacecraft ad hoc network technology and achieved remarkable results.This paper mainly sorts out the topological configuration,link characteristics and orbital configuration of spacecraft networking missions,and analyzes the characteristics and development trends of spacecraft networking.At the same time,the technologies that are applied to the field of spacecraft ad hoc network are intro-duced,including the time-frequency synchronous measurement technology based on node topology planning,the networking routing technology for active cognition of multi-domain information in the network,and the ad hoc network communication technology based on phased array agile beam pointing.Finally,some open issues and their development trends are also discussed,which can provide reference for subsequent researchers in this field.
