Abstract In order to avoid the communication tower unable to transmit signals caused by disastrous weather conditions such as rainstorm,and the regional automatic weather station cannot transmit rainfall and other data back to the central station,based on the actual case of Xingtai meteorological bureau installing TD204BD-M001 Beidou satellite communication terminal in the regional automatic weather station with severe rainstorm disaster,this paper analyzes the practical application of Beidou satellite communication system in the emergency transmission of regional automatic weather station data,supplemented by the Beidou emergency transmission of artificial observation rainfall data.It is found that the average timely arrival rate is 87%.Due to weather reasons or electromagnetic interference,the timely arrival rate is low.However,after retransmitting the data,the actual arrival rate is more than 98%,which can meet the needs of emergency transmission business of regional automatic weather station.
