2016年12月11日0时11分,中国在西昌卫星发射中心用“长征三号”乙运载火箭成功发射“风云四号”卫星。“风云四号”卫星实现了中国静止轨道气象卫星的升级换代和技术跨越,将对中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。“风云四号”卫星是中国静止轨道气象卫星从第一代(风云二号)向第二代跨越的首发星,也是中国首颗地球同步轨道三轴稳定定量遥感卫星,使用全新研制的SAST5000平台,设计寿命7年。卫星成
At 0:11 on December 11, 2016, China successfully launched the “No. 4” satellite at the Xichang Satellite Launch Center with the “Long March III” B carrier rocket. “The FY-4” satellite has achieved the upgrading of China’s geostationary orbit meteorological satellite and its technological leapfrogging. It will carry out high-temporal resolution, high-spatial resolution and hyperspectral resolution of atmospheric, cloud and space environments in China and the surrounding areas Of observations, a substantial increase in weather forecasting and climate prediction capabilities. The FY-4 satellite is the starting satellite for the China’s geostationary orbit meteorological satellite from the first generation (FY-2) to the second generation, as well as the first three-axis stable quantitative remote sensing satellite for China’s geosynchronous orbit. The newly developed SAST5000 platform, design life of 7 years. Satellite into
