北斗卫星应急通信传输试点建设

Construction of Emergency Communication Experimental System Using Beidou Satellite

根据福建省气象局开展北斗卫星应急通信传输试点工作的部署和要求,在南平市气象局选择3个有代表性的台站建设北斗卫星通信传输终端,分别在南平市气象局和福建省气象信息中心建设北斗卫星通信传输接收系统(中心站),并部署北斗通信中心站软件和终端软件,进行通信传输试点。利用北斗卫星通信系统传输国家级自动站观测数据、系统校时、文字通信功能均达到项目预期目标。传输率、误码率、时延和稳定性均能满足业务化运行的要求。实现公网运营商电路中断的应急状态下传输自动站观测数据和进行文字通信等,从而为防灾减灾服务。

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.
