An analysis was made of the development trend of meteorological satellite data transmission technology. The data transmission frequency of meteorological satellite is changing from L-band only to L-band and X-band plus K-band, adopting higher frequency and CCSDS package transmission. The convolutional multilevel R-S coding technology with advanced error correcting and antijamming capabilities is adopted, changing analog data into digital data. The data transmission characteristics of polar orbiting and goestationary meteorological satellites across the world are summarized to help data-receiving stations to make preparatory for receiving the new meteorological satellite data.
