Abstract

The paper proposes an open and shared sustainable mega-constellation with the "cloud-pool-terminal" paradigm and "Sensors+Network+AI" architecture, reshaping the satellite service mode and effectively solving the challenges of space environment sustainability.

Figure 1.
The co-construction, co-sharing and co-management paradigm based on the intelligent space system and intelligent satellites (a). Based on an open and unified SNAI architecture (b), iSat shares resources and builds a shared space resource pool (c, d), allowing countries around the world to jointly build a space system (e), join the space network to share satellite resources (f) and use the resource pool as needed (g). In (f) and (g), the different colors represent users in different areas, and the circled numbers denote the identification numbers of satellites. (f) and (g) represent the same satellites at different times (T0 and T1). Different types of users can access satellite networks at any point and anytime around the world, without being constrained by orbit, and enjoy real-time satellite resource services worldwide.
