陆上节点地震勘探仪器同步授时的实现方法

Realization method of synchronous timing of land node seismic instrument

节点仪器在野外自主完成地震数据采集工作.每个采集站利用卫星时钟系统校准同步本地时钟系统,从而为连续记录的地震数据标记精确的卫星时间.时钟同步系统是节点采集站最重要的系统.本文介绍了基于卫星时钟系统的节点采集站时钟同步授时的实现方法.

Node instrumentcompletes seismic data acquisition independently in the field.Each node calibrate synchronous local clock by satellite time system,acquired accurate time to mark continuously record seismic data.Clock synchronization system is the most important system of node acquisition system.This paper introduces the method of node instrument lock synchronous system based on satellite clock system.
