摘要
北斗三号系统是我国独立自主建设的全球导航卫星系统,云平台是其地面系统的重要组成部分,用于实现软硬件资源的统一管理、按需共享与实时动态调配。本文依据工程实践介绍了北斗三号云平台系统的架构及使用流程,总结了云平台建设过程中的代表性技术攻关情况以及系统上云后效能提升情况。针对下一代卫星导航系统服务种类多样、服务信息按需定制、服务能力安全可靠等趋势,从开发运维模式上提出了导航地面系统业务融合云原生技术的考虑;从基础设施结构上提出了分阶段实现导航地面云全面自主可控的建议。最后展望了下一代导航地面系统云平台架构,初步构想云架构由分散、独立云节点向一体化云转变,实现由云中心、网络、端共同组成的导航系统地面云,以进一步提升导航地面系统的运管效能和地面中心的容灾抗毁性。
BeiDou No.3 System is a global navigation satellite system built by China independently.The cloud platform,realizing the unified management,on-demand sharing,and real-time dynamic allocation of software and hardware resources,is essential to the BDS-3’s ground system.This paper introduces the architecture and process of BDS-3’s cloud platform based on engineering practice and summarizes the representative technical breakthroughs in the cloud platform construction and improvement.The trend of the next generation satellite navigation system is diverse in service types,customized on service information,safe and reliable on capability.The integration between cloud-native technology and the business of navigation ground systems is put forward to improve the efficiency of development and operation;from the perspective of infrastructure structure,it is suggested that the navigation ground cloud be fully autonomous and controllable in stages.Finally,we look forward to the cloud platform architecture of the next-generation navigation ground system.The system architecture,composed of a cloud center,network and terminal,transforms from the construction of independent nodes to the unified construction of all distributed nodes.The navigation ground system will further improve operation and management efficiency and the disaster tolerance and survivability.
