Abstract:
In order to meet the requirements for establishing the pilot emergency communication system by means of Beidou satellites, the Nanping Meteorological Service selected three representative stations as Beidou satellite communication terminals. The Beidou satellite communication receiving systems were built in Nanping Meteorological Service and the Fujian Provincial Meteorological Information Center, and both the software of Beidou communication center and the terminal software were deployed. By using the Beidou satellite communication system, the transmission of text messages and observation data of national automatic stations and system time correction are released.The trail application indicates that the transmission rate, error rate, delay, and stability all meet the requirements for operational running. Under the emergency condition such as the interruption of the public network, the automatic station observation data and text messages can still be transmitted properly.
