Abstract: After 50 years of development, China has become one of the few countries that maintain both polar and geostationary meteorological satellites operationally in the world.China’s FengYun (FY) Meteorological Satellites data are shared globally and open to global users for free, therefore FY satellites system has become a key component of the WMO space observation program.There exist two wings leading to the high-quality development of FY meteorological satellites, the independent and controllable localization path, and the open and cooperative internationalization path.This paper focuses on reviewing the integration process of China's FY meteorological satellite with the international earth observation system after entering a new era, responding to the Vision Plan 2025 of the Global Observation System (GOS) released by WMO in 2009.Based on the Vision Plan 2040 of the WMO Global Integrated Observing System (WIGOS) released in 2019, the future development direction and technical trends of China’s FY meteorological satellites are discussed as well.
