摘要
介绍了风云二号(FY-2)静止气象卫星02批首颗业务应用C星的构型与布局、控制分系统、5通道扫描辐射计、星上图像生成、数传与云图广播转发器、工程与业务测控、二次分离、电源母线调节、复合材料结构件和仪器板等温化等主要技术特点。给出了C星相对01批的多通道扫描辐射计、无线系统和电源等部分技术改进。在轨测试与运行结果表明,C星的成像系统达到了研制总要求和任务书指标,云图观测能力和质量满足气象卫星业务运行及应用系统的需求。自投入业务运行后,C星为国内外用户提供了大量的图像、定量与人机交互产品,在暴雨、台风、火灾和海冰等监测中发挥了重要作用。最后,对静止气象卫星的发展趋势进行了展望。
The main technology characteristics of FY-2C satellite, which was the first one in the second batch of FY-2 geostationary meteorological satellite, such as construction and layout, control subsystem, 5 channel scanning radiometer, satellite-borne image forming, transponder of data transmitting and clouds image broadcasting, telemetry and control of engineering and service, the second separating, power bus regulation, composite structural member, and isothermal of instrument board were introduced in this paper. The major improvements of multi channel scanning radiometer, radio and power for C satellite were aiso presented. The on-orbit test and operation result showed that the imaging system of C satellite met the requirement of research and rni.~sion, The observation ability and quality of clouds image for C satellite satisfied the requisite of the operation and application system. C satellite had provided large amount of image products, numerical products and man-machine interactive products since it began to operate, which played an important role in the monitoring of hard rain, typhoon, fire and sea ice. At last, the development trend of geostationary meteorological satellite was prospected.
