摘要
随着信息通信和航天技术的飞速发展,空间网络相关技术日趋成熟,全球信息化发展领域已全面拓展到人类生产、生活和科研的所有空间,包括陆地、海洋、天空和太空。对于我国而言,加快建设天地一体化信息网络,通过天地网络配合实现全球无缝覆盖的目标,是信息网络发展的重点。给出天地一体化信息网络的组成、网络形态与主要特点,研究归纳国内外天地一体化信息网络的发展现状与趋势,并分析给出建设天地一体化信息网络需要突破的关键技术,希望为我国天地一体化信息网络的研制和建设提供借鉴与参考。
With the rapid development of ICT(information communication technology)and aerospace technology,the space network related technology is becoming mature,the global promotion of information technology fi eld has been fully expanded to all the space of human production,life and scientifi c research,including land,ocean,sky and space.For the China's information network,it is the focus to speed up the construction of the space-integrated-ground information network and realize the goal of seamless global coverage through the cooperation of the heaven and earth network.Firstly,the composition,network form and main characteristics of the space-ground integrated information network were described.Then,the development status and trend of the space-integrated-ground information networks at home and abroad were summarized.Finally,the key technologies needed to break through in the construction of the space-integrated-ground information network were analyzed,Hoping to provide reference for the development and construction of the space-integrated-ground information network.
