摘要
针对地震勘探中采集道众多,地理信息获取不精确,采集道定位精度差的问题,设计了基于GPS的地震勘探的差分定位系统。通过对差分定位原理的深入分析,设计了地震采集道的定位系统,并在此基础上,将基准GPS基站发送的RTCM差分信息,传输至地震采集道进行差分运算得到了差分后定位数据。最后,利用实际的地震勘探环境对差分定位的结果进行了测试,结果表明,该系统具有良好的精确度和可靠性,满足了地震勘探过程中对获取高精度地理信息的要求。
In seismic exploration acquisition way is numerous,geographic information acquisition is not accurate,acquisition problem of poor positioning accuracy,seismic exploration based on GPS differential positioning system is designed.Through in-depth analysis of the principle of the differential positioning,design the seismic acquisition way of positioning system,and on this basis,the benchmark of GPS base station sends RTCM differential information transmission to the seismic acquisition way for difference operation after differential positioning data are obtained.Finally,using the actual seismic environment was tested,the results of the differential positioning results show that the system has good accuracy and reliability,to satisfy the seismic exploration process to obtain high accuracy requirements of geographic information.
