Baseband pool technology based on embedded cloud platform for data relay satellite system ground terminal station

For the application status of the TT&C and communication equipment of data relay satellite system ground terminal stations with various types,strong specificity,and weak interoperability,an embedded cloud platform deployment scheme and panoramic dynamic reconstruction technology roadmap based on blueprint technology are proposed through researching on the open platform architecture of ground stations,so as to solve the problems that the baseband functions of the ground terminal station can be expanded,the terminal can be flexibly reconfigured,the computing resources can be configured on demand,the business functions can be customized online and the quick handover can be performed.A prototype is developed and a demonstration experiment is conducted.The network interconnection rate reaches 40 Gb/s,5 sub-particles and 32 micro-particles get access,and successfully deploys 4 functions.A single function reconstruction time is 30 seconds.Compared with traditional TT&C and communication baseband equipment,with the same construction cost,processing capacity is increased by more than 5 times.The experimental results show that the proposed technology can greatly improve the ability of the ground terminal of the data relay satellite system to adapt to wartime rapid response and mobile deployment,and effectively reduce the cost of equipment R&D,operation and maintenance and future performance upgrade.
