FY-4
Feng Yun-4 series is China's second generation geostationary meteorological satellites. It is planned to launch in 2016. According to Li Qing, Chief Engineer of scientific experimental satellite, compared with Feng Yun-2, the performance of Feng Yun-4 has been improved in terms of data amount, network transmission bandwidth, product type and quantity and archiving data and applications.

It would take over the business of Feng Yun-2 satellite. 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 enabled with vertical atmospheric sounding and microwave detection capabilities to address 3D remote sensing at high altitudes. It is also enabled with solar observations for extreme ultraviolet and X-rays, in a bid to enhance China's space weather watch and warning capability.

FY-4 will be made either carrying optical or microwave instruments. An optical satellite will carry onboard a 10-channel 2D scanning imager, an interferometric vertical detector, a lightning imager, CCD camera and an earth radiation budget instrument. The satellite produces earth disc imageries every 15 minutes.
Features
ㆍAdvanced Geosynchronous Radiation Imager (AGRI). The instrument has 14 channels with a spectral range set between 0.55μm and 13.8μm.
ㆍGeo. Interferometric Infrared Sounder (GIIRS).·Lightning Mapping Imager (LMI).
ㆍSpace Environment Package (SEP).
ㆍSolar X-EUV imaging telescope (SXEUV)
ㆍData Collection Service (DCS)
