Design of space-based intelligent information system based on LEO constellation

Conducted research and analysis on existing foundation information systems, and analyzed the requirements and existing shortcomings of future information systems. A space-based intelligent information system based on LEO constellation was proposed, which was designed from three aspects: overall system, constellation orbit, and measurement and control link, and its feasibility was analyzed. A fast collection method for regional information based on wireless sensor networks is proposed for ground terminals. The protocol stack of wireless sensor networks is designed for high bandwidth and low bandwidth regional perception needs, and network integration design is carried out for wireless sensor networks and spacebased systems.
