3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Stretched VISSR data ; S-VISSR
The 14 Mbit/s raw image data of the Visible Infrared Scan Radiometer (VISSR) carried by the Fengyun-2 geostationary meteorological satellite acquired by the ground application system, after data processing to stretch the transmission time and reduce the code rate to 0.66 Mbit/s, is forwarded to users in real time via satellite via satellite with information such as calibration and positioning.
3.2
Low noise block downconverter; LNB
In satellite communication systems, a special device used to convert satellite radio signals transmitted by the feed source into voltage and current signals, and to amplify and down-convert the signals to meet the needs of subsequent transmission and reception.
