摘要

Water vapor monitoring system by Beidou satellite is a new detection system in meteorological department,which makes receiving amount of detected data and data storage and transmission pressure increase. Here,we try to use data compression to relieve pressure. Compression software of water vapor monitoring system by Beidou satellite can be designed into three components: real-time compression software,check compression software and manual compression software,which respectively completes the compression tasks under real-time receiving,in-time check and separate compression,thereby forming a perfect compression system. Taking the design of manual compression software as guide,and using c language to develop,compression test of original receiving data is conducted. Test result proves that the system can carry out batch automatic compression,and compression rate can reach 30%,which can reach the target of saving space in a degree.
