[Abstract] 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. Finally, we consider that key technologies such as network architecture, satellite constellation, integrated networking of space and terrestrial, transmission, network management and safety should be solved during the construction of space broadband internet.
