Fengyun 6
China Meteorological Administration (CMA) is operating FENGYUN (or FY for acronym) geostationary and polar-orbiting satellite systems. Currently, six FY satellites are on-orbit with well performance, including four geostationary meteorological satellites and two polar orbiting meteorological satellites. FY satellites take place in series. The odd number series are the polar-orbiting, while the even number series are the geostationary. The capital letter after the serial number refers to the seat of a particular satellite in the launching sequence.
Consistent with the WMO Integrated Global Observing System (WIGOS) in 2040 for the space-based observing system component, an integrated observing system of Fengyun weather and climate satellites will be established by 2035, which is a backbone system with specified orbital configuration and measurement approaches, composed of FY-5 polar-orbiting and FY-6 geostationary meteorological satellites.
FY-6, the third generation geostationary meteorological satellites, will enable the integrated observation capability of FY satellites to reach the world"s leading level. The Radiometric Benchmark Satellite mission aiming to establish stable and traceable space calibration reference will be developed as well.
Meanwhile, a backbone system with open orbit configuration and flexibility to optimize the implementation will be developed, which is composed of some small/ large satellites programmes for dedicated-objective mission with the capabilities of higher temporal and spatial resolution and fast sampling, global cloud, aerosol, wind etc. dedicated observation, to meet the requirements of weather forecasting, meteorological risk reduction and emergency response promotion. Furthermore, the operational pathfinders, technology and science demonstrators will be explored to respond to R&D needs.
