我国成功发射风云四号气象卫星
China successfully launched the Fengyun-4 satellite last Sunday from the Xichang Satellite Launch Center in Sichuan, marking an upgrade for China's meteorological satellites in geostationary orbit. The satellite was taken into orbit by the Long March-3B carrier rocket.
上周日，我国在四川西昌卫星发射中心用长征三号乙运载火箭成功将风云四号卫星送入轨道，这标志着我国静止轨道气象卫星的升级换代。The Fengyun-4 satellite, the first of China's second-generation weather satellites in geostationary orbit to be launched, is also the country's first quantitative remote-sensing satellite in high orbit.
风云四号卫星是我国第二代静止轨道气象卫星的首发星，也是我国首颗高轨道定量遥感卫星。The satellite will make high time, spatial and spectral resolution observations of the atmosphere, clouds and space environment of China and surrounding regions, significantly improving capabilities of weather and climate forecasts, according to the State Administration of Science, Technology and Industry for National Defense.
据国家国防科技工业局介绍，风云四号卫星将对我国及周边地区的大气、云层和空间环境进行高时间分辨率、高空间分辨率、高光谱分辨率的观测，大幅提高天气预报和气候预测能力。
The China Meteorological Administration is the primary user of the satellite.
风云四号卫星的主用户为中国气象局。Fengyun-4 innovatively achieves integrated payload configuration. Such elaborated designation can multiply the function of Fengyun-4 while substantially cutting down on the research and development costs.
风云4号卫星创新性地实现了集成的有效载荷配置。这样精心的设计可以成倍的提升风云4号的功能，同时还可以大幅削减研发成本。Traditionally the imager and sounder are carried by different satellites to prevent mutual interference. However, Fengyun-4 successfully overcame this tough problem in the world and various instruments onboard can peacefully work on the same platform without upsetting each other.
传统的图像和声音信号都是由不同的卫星来运载的，以此来防止相互干扰。不过，风云4号卫星成功地克服了这个世界性的棘手问题，各种仪表板可以在同一平台上正常运行，而且不会互相干扰。"What's more, it realizes comprehensive observations of atmosphere with various means for the first time in the world." Yu Xinwen, Deputy Administrator of China Meteorological Administration (CMA) and commander-in-chief of FY-4 satellite program said.
中国气象局副局长、风云4号卫星项目的总负责人于新文表示：“更重要的是，该卫星在世界上首次实现了对大气的多手段综合观测。”
