Abstract: The chief use of meteorological satellite data is in weather forecasting。 The successful forecasts require the observations of the atmosphere which are both detailed and up-to-date. It is necessary to rapidly collect the widespread data and to distribute the processed data to widespread users, so the meteorological services require that the geostationary meteorological satellite has two functions at least One is the meteorological observation, the other is the meteorological communication. Both of them are posessed of equal importance. Three-axis stabilized geostationary meteorological satellite has more advantages than the spin-stabilized geostationary meteorological satellite. It has better time-efficience, but less band width of the baseband signal of the original information, and better Noise Equivalent Temperature Difference (NEAT) for the infrared channels as well as better ratio of signal to noise (S/N) for the visible channels. It is applicable to meteorological observation and remote-sensing instrument which will be installed in the geostationary meteerological satellites in future, and it has nore communication capabilities for meteorological services。
