Abstract:

The demand of new marine applications,such as ocean observation,polar scientific research,autonomous ship navigation,ship dynamic tracking,etc.,for the space-integrated-ground information network was analyzed.The typical marine applications,such as ocean remote sensing data relay,space-based internet of things of ocean observation platform,safety supervision of ships in the middle and far seas were proposed.Through the demonstration and promotion of the space-ground integrated information network marine application,we can promote the eff ective integration of the marine application and the Space-Ground Integrated Information Network,improve the comprehensive level of marine informatization,and help the rapid and stable development of China’s marine economy.

Key words: space-ground integrated information network, the marine application, marine informatization, space-based relay, space-based internet of things
