应用于地震预警系统的实时高频GPS接收与处理软件设计

Real time high frequency GPS receiving and processing software design applied to the earthquake early warning system

针对高频GPS实时处理技术在地震预警系统中的应用要求,对GPS数据实时数据接收、处理等关键技术进行研究,研发了应用于地震预警系统的实时高频GPS接收与处理软件.软件具有实时GPS数据与地震数据同步接收、实时GPS数据定位、数据存储、网络数据服务等功能.本文详细介绍了软件架构和RTCM3.1格式实时GPS数据流的解码方法、实时GPS定位软件TrackRT软件在本软件中的应用.

According to the requirement of high frequency GPS real time processing technology application in earthquake early warning system（EEW）,researching on key technology of high frequency GPS data receiving,real-time processing et.,developing the software applied to the EEW.The software has fowling functions：receiving the real-time GPS data stream and the seismic data stream,GPS data processing real-timely,data storage,network data service and so oa The software structure is introduced,the method of decoding the real-time GPS data stream（RTCM3.1 format） and the application of real time GPS software TrackRT in this software are presented in detail in the paper.
