Research on the Key Functions and Development of Mega-constellation Information System
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.
