FY-2C Geostationary Meteorological Satellite and Its Development Prospect

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 also presented.The on-orbit test and operation result showed that the imaging system of C satellite met the requirement of research and mission.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.
