| 摘 要： | 从模拟地震观测到数字地震观测,地震事件的时间标识一直是地震观测中的关键技术之一。当一个地震事件发生时,模拟观测时代是通过短波授时和校时技术为地震事件标识时间,而数字观测时代则是借助于精度更高的全球定位系统(Global Position System,简称GPS)为地震事件标识时间。本文详细介绍地震数据采集器中的GPS授时技术和校时技术。

| Abstract: | From analog seismic observation to digital seismic observation, time label of earthquake event is always one of key technology in seismic observation. When an earthquake event occurred, time label for it is completed by shortwave timing during analogy observation. However, it is completed by global position system （GPS）. In this paper, the technology of GPS timing and correcting-time in earthquake data acquisition device is described in detail. |
