Fengyun 4A



Fengyun-4 (Wind and Cloud) series is China’s second-generation geostationary meteorological satellites after Fengyun-2 satellite series. The performance of Feng Yun-4 has been improved in relation to FY-2 in terms of data amount, network transmission bandwidth, product type and quantity and archiving data and applications. The satellite attitude is three-axis stabilized to improve the time resolution of observations and regional mobility.

The new generation satellites are designed with an enhanced imagery scanning capability, desirable for monitoring small and medium scale weather systems. It is equipped with vertical atmospheric sounding and microwave detection capabilities to address 3D remote sensing at high altitudes.

The satellite also carries instrumentation for solar observations for extreme ultraviolet and X-rays, in a bid to enhance China’s space weather watch and warning capability. The main instruments on Fengyun-4A are the Advanced Geosynchronous Radiation Imager (AGRI), with 14 channels with a spectral range set between 0.55µm and 13.8µm; the Interferometric Infrared Sounder (GIIRS); the Lightning Mapping Imager (LMI); the Space Environment Package (SEP); the Solar X-EUV imaging telescope (SXEUV); and the Data Collection Service (DCS).
