Known as the “ Li Mingxing ” Fengyun No. 3 E Star in 2021 year 7 month 5 Successful launch on , It is the world's first civilian dawn dusk orbit service satellite , Including 3 A newly developed instrument 11 Type payload , It fills the gap in the observation of satellite data of the global numerical weather forecast model in the morning and dusk periods . Fengyun 4 B Star in 2021 year 6 month 3 Successful launch on , It is the first operational satellite of the new generation geostationary meteorological satellite in China , In succession to Fengyun 4 A Optimization design is carried out on the basis of mature technology of star test star , Fully tap the satellite platform and payload capacity , The overall reliability of the satellite is improved 、 Stability and detection accuracy , And add a new fast imager , Have minute level 250 M resolution area imaging capability .
Fengyun 3 E star 、 Fengyun 4 B The satellite and its ground application system were launched this year 6 month 1 Business trial run on the day of . After business operation , Fengyun 3 E Star and Fengyun III C Seiwa D Star implementation samsung networking , Every time 6 Hour provides a complete observation data covering the whole world for the numerical prediction model , Effectively improve the accuracy and timeliness of global numerical weather forecast , It is of great significance to improve the global earth observation system ; Fengyun 4 B Star and Fengyun IV A The star realizes the double star networking , To further meet the needs of China and “ the Belt and Road ” The countries and regions along the line shall monitor and forecast the weather 、 Service demand for emergency disaster prevention and mitigation .
During on orbit testing , Fengyun 3 E Star has successively released “ Li Mingxing looks at the sun ”“ Li Mingxing looks at the atmosphere ”“ Li Xingxing looks at the earth ” And other three batches of observation products , stay “ Lanina ” event 、 Polar glaciers melt 、 It plays an important role in the monitoring of solar eruptions and typhoons ; Fengyun 4 B The satellite provides support for the Winter Olympic meteorological services by using high spatial-temporal resolution images, snow and other quantitative products , In the founding of the Communist Party of China 100 Anniversary celebration 、 The 14th National Games and other major activities played a role in service guarantee and monitoring of Tonga volcano eruption and other international hot events .
Up to now , China has successfully launched two generations 4 type 19 A weather satellite , among 7 On orbit operation , As an important part of the WMO global operational application meteorological satellite sequence and the duty satellite of the international charter mechanism for major disasters , Is continuing to serve the world 124 Countries and regions provide data products and services .
In the future, the China Meteorological Administration will continue to promote the Fengyun meteorological satellite to WMO And its members' contributions to disaster prevention, mitigation and climate change response .
