16 Apr 2023: The China Meteorological Administration (CMA) launched a Long March-4B with the Fengyun-3G (FY-3G) meteorological satellite from the Jiuquan Satellite Launch Center in northwest China. The FY-3G will act as a vital component in global precipitation detection under the WMO framework. Launch Video.

– FY-3G is equipped with a Ku/Ka-band dual-frequency precipitation measurement radar, microwave imager, optical imager and near-infrared multi-angle polarization imager. The precipitation measurement radar is a first-of-its-kind instrument, developed independently by China.

– FY-3G is the 20th Fengyun meteorological satellite in the series and will help improve early warning capabilities for monitoring weather- and climate-related disasters.

– FY-3G is in a much lower orbit than other FY-3 satellites likely to support its radar. FY-3G is in a 416.4x408km orbit and is inclined at 50°. The other FY-3 satellites are all in orbits at >820km and are inclined 97° (sun synchronous orbit).

– All previous FY-3 used CZ-4C and all but FY-3E and now FY-3G were launched from Tiayuan. 3E/3G were both launched from Jiuquan.

-FY-3G will carry out in-orbit testing over the next six months, with China set to launch another FY-3 meteorological satellite in Aug 2023. China has eight FY meteorological satellites in orbit, providing data products and services for 126 countries and regions.

China has launched 6 Fengyun satellites since 2016, FY 2H, 3D, 4A, 4B, 3E and 3G. The China Meteorological Administration plans to launch Fengyun-3F to Fengyun-3J, as well as Fengyun-4C to Fengyun-4G in the upcoming years and decades, covering their need for meteorology satellites until 2040, with the last satellites planned to launch in 2030 and 2033 respectively.
