The BeiDou Meteorological Warning Information Distribution System (BMWIDS) is a new type warning information distribution system established by the China Meteorological Administration， which is supported by a project Atmosphere Marine and Space Monitoring Early Warning Application Demonstration Project Based on BeiDou Navigation Satellite SystemThis system uses Beidou satellite to distribute warning information in broadcast manner with enormous coverage and guaranteed timelinessIn 2015, BMWIDS began trial operation in Hubei Province with 140 Beidou warning terminals installed and used in Zigui CountyThis paper introduces the system architecture and key technology of BMWIDS, and illustrates its application in Zigui in three aspects: terminal installation, service management, and information distributionThe key technology of BMWIDS includes satellite broadcast, encoding and protocol, message compensation and error correction, as well as service configurationThe comparison is conducted between BMWIDS and other distribution media currently used in Zigui, which are mobile short message, meteorological loud speaker and meteorological LED screenThe service capability and management level of Zigui meteorology are improved by the application of BMWIDSIt is a valuable experience for the implementation and operation of warning information distribution systems based on Beidou satellites in the future
