摘　　要：从天基宽带互联网的概念出发,在详细研究了全球天基宽带互联网发展现状与研究进展的基础上,提出中国天基宽带互联网应依据国家现实需求,遵循近期、中远期渐进的路线演进。同时认为在天基宽带互联网发展过程中,必须解决网络体系架构、卫星星座、空间与星地一体化组网、传输、网络管理与安全等关键技术问题。In this paper, we firstly describe the concept of space broadband internet. Then after studying the status and development trend of space broadband internet both in abroad and domestic, we propose that the space broadband internet of our country should be developed according to the road map of the near future to medium/long-term in order to meet the country ’s actual demands. Final y, we consider that key technologies such as network architecture, satel ite constel ation, integrated networking of space and terrestrial, transmission, network management and safety should be solved during the construction of space broadband internet.
