CFOSAT is an Oceanography dynamics remote sensing satellite developed under international cooperation between China and France. It is the first satellite in the world to provide joint simultaneous and co-located observations of ocean surface wave spectrum and wind field at the global scale. It will play an important role of benefiting in several domains, such as ocean dynamic circumstance surveillance, ocean weather forecast, ocean climate science research. Two science payloads are designed onboard: SWIM for wave monitoring, and SCAT for wind observation. In this paper, we introduce the information of CFOSAT system design, development process, technical characteristics and international cooperation.
