| 中文摘要: |
| 风云三号（简称FY-3）是中国第2代极地轨道气象卫星系列。它的第1颗星——风云三号A星（FY-3A）于2008年5月27日上午11时02分33秒在山西太原卫星发射中心发射升空。
新一代极轨气象卫星主要是实现全球、全天候、三维、定量、多光谱遥感，以满足现代气象业务，特别是数值天气预报业务的发展，同时监测大范围气象及其衍生自然灾害和生态环境变化，为研究全球气候变化规律，进行气候诊断和预测提供地球物理参数，为农、林、交通、海洋、水文等多领域提供服务。FY-3A携带11个对地观测仪器，其观测数据通过星地链路进入地面接收站，并在数据处理和服务中心（国家卫星气象中心大楼内）汇集。在强大的计算机和网络支撑下，利用科学算法对仪器遥感数据进行处理，生成各类产品，提供给用户使用。
FY-3A发射后，经过半年的在轨测试和试运行，于2009年初正式投入业务运行，卫星和地面系统状态稳定，工作正常。文中较系统全面地介绍了卫星轨道、数传、仪器、数据接收、处理和产品等，尤其分析了星载仪器的主要技术特征，并给出了部分产品应用实例 |
| 英文摘要: |
| FY-3 is the second generation polar orbiting meteorological satellite series of China. The first satellite named FY 3A of this series was launched from Taiyuan in Shanxi Province at 03:02 UTC on 27 May 2008.The new generation satellites series are to provide three-dimensional, quantitative,multi spectrum global remote sensing data under all weather conditions,which will greatly help the operational numerical weather prediction，global change research，climate diagnostics and prediction，and natural disasters monitoring.They will also provide help for many other fields such as agriculture，forestry，stock raising, oceanography, hydrology and so on.
Observations from all of the 11 instruments aboard this satellite are broadcast on L and X bands. Ground receiving stations operated by National Satellite Meteorological Center (NSMC) receive the data from FY-3A and then send the data to Center of Data Processing and Service (CDPS) at NSMC in Beijing routinely. The remote sensing data are processed by using various algorithms and different kinds of products are generated routinely with the high-speed computers and networks of NSMC. The data and products are available to users worldwide.
The trial run of FY-3A took about six months following its launch. FY-3A has been officially in operation since January 2009. This paper introduces the FY-3A platform, data transmission, payloads, and products. Major technical peculiarity and application examples are given as well. |
