Abstract: After years of research and development, space-ground integration information network (SGIN) is still in the initial stage. Although the country has yet established a truly global space-based Internet, the development of frontier technology makes the space-based network feasible. In this paper, we proposed a novel system architecture of SGIN adopting the cuttingedge technologies of new communication transmission, plug and play satellite module, flexible configuration effective carrier, modular network system, and multi-satellite launch. The paper further analyses the role of new technologies in promoting space-based networks from the aspects of performance and cost and puts forward the development trend of space-based network technology. Finally, we identified and summarised some common misunderstandings and promising trends of SGIN. With the novel architecture design and demonstration of the promising trends, we believe this paper will guide the future research of high-impact research in SGIN.

Keywords: SGIN; space-ground integration information network; flexible payload of satellite; plug and play; space optical communication; space quantum communication.
