| 摘 要： | 介绍了NASA空间通信体系工作组(SCAWG)所提出的2005～2030年NASA空间通信与导航体系。该体系包括地基地球、近地中继、月球中继和火星中继4个物理单元,以及叠加在这4个物理单元之上的网络、安全、频谱及导航4个贯穿的公共体系。为实现这一体系,SCAWG提出了未来6大关键的技术领域,包括上行链路组阵、光通信、航天器RF技术、X射线导航、网络技术和可编程通信系统(软件定义无线电)。通过对NASA未来空间通信与导航体系及关键技术领域进行研究,可为未来的空间探测活动及相关技术发展提供参考。

| Abstract: | The paper introduces the NASA Space Communication and Navigation Architecture for 2005～2030 developed by Space Communication Architecture Working Group (SCAWG).This architecture consists of four physical elements including ground-based earth element,near-earth relay element,lunar relay element and Mars relay element,with overlaying network,security,radio frequency (RF) spectrum and navigation architectures.The six technology areas enabling the future architecture are uplink arraying,optical communications,spacecraft RF technology,X-ray navigation,network technology and programmable communications systems (software defined radio).The study on this architecture and the relevant technologies may provide reference for the space exploration and technical development of China in the future. |
