Abstract: Computer Network and Storage(CNS)system is an important component of the meteorological satellite engineering.CNS supplies resources and environments for the satellite in-orbit management, satellite observation data receiving, processing, archiving and service.Since the first geostationary meteorological satellite was launched, the scale of the computer network of the ground segment has been greatly expanded; its architecture has experienced nearly twenty years of rolling development and continuous improvement.In this paper, the development process and the results are reviewed.The opportunities and challenges of CNS construction are well analyzed.Finally, based on the flexible job and resource scheduling technology, a new structure with high scalability and reliability of CNS for FY-4Ageostationary meteorological satellite is raised up.
