China Launches Fengyun-4C Weather Satellite to GEO

26 Dec 2025: China launched a Long March-3B rocket with the FengYun-4C (67246) meteorological satellite from Xichang. FengYun-4C will operate in GEO over 133°E longitude. The same sources report FY-4C is the replacement for FY-4A which has been in GEO since 2016. Launch Video. Watch Promo Video.

– FY-4C is a 5,300kg satellite which will support China’s National Satellite Meteorological Center (NSMC).

Per the NSMC, FY-4C “will replace the FY-4A satellite, which has exceeded its service life in orbit”

– Fengyun-4C is planned to be in operation for the next eight years, and will be located at 133°E longitude “with an observation area ranging from 68°E longitude to 162°W longitude, covering most of my country and the Asia-Pacific region.”

– FY-4A, the satellite FY-4C is replacing. is located at ~124°E longitude, it will be interesting to see if China leaves the satellite in place or increases its SMA to place it into a graveyard orbit.

Per China In Space: “The Shanghai Academy of Spaceflight Technology stated that they developed Fengyun-4C and added that new capabilities are onboard, like small electric hall-effect thrusters, installed on manipulatable arms, for fine orbital adjustments. Improved space-to-ground communications were noted alongside the capability for space-to-space-to-ground7 communications in the near future.”

– FY-4C is the 3rd satellite in the geostationary Fengyun-4 series (a follow up from the FY-2 series).

– Readers may be most familiar with FY-1C which China destroyed with a Direct Ascent ASAT missile in 2007. Thousands of pieces of debris remain in orbit from that test and will be a threat for generations to come (nice going guys).

– This is the second FY satellite China has launched in 2025. They also launched FY-3H into a LEO sun-synchronous orbit on 26 Sep 2025.

– There are currently 13 active Fengyun satellites in orbit (including FY-4C). 5 in GEO and 8 in LEO.

  • LEO
    • FY-3A (2008); FY-3B (2010); FY-3C (2013); FY-3D (2017); FY-3E (2021); FY-3F (2023); FY-3G (2023); FY-3H (2025)
  • GEO
    • FY-2G (2014); FY-4A (2016); FY-2H (2018); FY-4B (2021); FY-4C (2025)
