巨型星座信息系统核心功能及发展研究

Focusing on solving the four major challenges of mega-constellation fusion networking，security & trust，task collaboration and the whole life cycle management of intelligent application software development on board，the analysis concludes that the mega-constellation information system is the core to break through the four challenges. Then，the research status of core functional requirements such as robust controllable networking of mega constellation nodes，secure node access authentication，real-time collaboration of multi-node tasks and intelligent application capability generation is investigated. Based on the research results and combined with the application requirements of future space-based systems，four development directions of mega-constellation information system were summarized and refined. A hierarchical unified architecture of mega-constellation information system is proposed，which lays a foundation for solving the problem of "two differences and two weaknesses" of existing information systems and meeting the application requirements of complex scenarios of mega constellation.
