低轨星座地面通信应用系统初步设计
|
摘要
随着全球互联网和物联网服务的延伸,可以实现包括南北两极在内全球无缝覆盖的低轨星座又一次进入了发展机遇期,低轨星座的发展带来地面5G移动通信和高通量宽带接入通信的迅猛发展,来满足广大终端用户的大容量通信需求。提出天地一体化信息网络中地面通信应用系统的初步解决方案,主要从系统组网架构、数据运营中心、信关站系统、终端系统以及系统安全性、可靠性等方面进行设计,对于低轨星座地面通信应用系统的研制发展具有一定参考意义。
With the extension of global Internet and IoT services,the Leo constellation that can achieve global seamless coverage,including the North and South poles,has once again entered the development opportunity period.The development of Leo constellation has brought about the rapid development of ground 5 G mobile communications and HTS broadband access communications,thus meeting the largecapacity requirements of terminal user communication.One preliminary solution for ground communication application system is proposed in the space-earth integration information network.And the design is done mainly from the aspects of system network architecture,data operation center,gateway station system,terminal system and system security and reliability.All this is of certain reference significance for the development of low-orbit constellation ground communication application system.
