[Abstract] The terrestrial information system is unable to fully meet the requirement for wide coverage and multi-class information fusion of information-based society and national defense，and the establishment of space information infrastructure is the development needs of the future information network. In this paper, aiming at the reasons, network architecture, technical difficulties and demonstration of the construction of space/sky/terrestrial integrated information network in China, we propose some considerations about the construction of network and some views about technical difficulties which are different from land information facilities.
