虚拟化测控站体系结构设计与关键技术

Satellite Ground Station Virtualization:Architecture and Key Technology

随着测控任务日渐密集,任务类型的多样性、复杂性不断增长,传统测控站封闭的体系结构在应对未来测控需求方面存在较多的技术短板。在对比分析国内外同类技术发展的基础上,提出了以综合基带虚拟化和软件定义网络技术为基础、以资源池为核心的新一代测控站体系结构,分析了测控站功能域与实现方法,设计了基于OpenFlow协议的测控站网络。设计了多星测控实验,验证了虚拟化测控站的优势。实验结果表明,当前商用设备的虚拟化率不低于1. 25。

Telemetry,tracking and command(TT&C) tasks are becoming more and more intensive,and the diversity and complexity of task types are increasing. There are many technical shortcomings for the traditional closed and outdated satellite ground station architecture to meet the future TT&C requirements. According to the comparative analysis of the development of similar technologies at home and abroad,a new generation of TT&C station architecture is proposed,which is based on the integrated baseband virtualization and software defined network technology and takes resource pool as the core. The functional domain and implementation method of the TT&C station are analyzed,and the TT&C station network based on OpenFlow protocol is designed. A multi-satellite TT&C experiment is designed to verify the advantages of the virtual TT&C station. The experimental results show that the current virtualization rate of commercial equipment is no less than 1.25.
