Abstract:The method for designing a key SMS monitoring platform of Fengyun3 meteorological satellite data processing system is proposed. The selection of key monitoring positions, the intelligent identification of orbits, the processing of alarming messages, and the way to guarantee high realtime performance are discussed. Based on the detailed analysis of orbit characters, two orbitsidentification algorithms are proposed and discussed. Besides, a SMS filter logic and high efficiency software architecture is adopted to guarantee realtime performance. The operation statistic results are given.
