GPS在地震勘探仪器中的应用
|
摘要
文章介绍了GPS秒脉冲信号和差分GPS在物探仪器中的应用。为了能够严格同步发射地震波、采集反射波,在具体应用中使用了恒温晶振和锁相环集成电路;为了使数据采集更有实效,数据之间联系更强,需要把集成了GPSOEM的仪器阵列布局,通过DGPS,仪器的布局更为准确和严格,操作起来也很方便。仪器集成GPSOEM后通过规模化布局,采集数据更为便捷,数据之间联系也更方便,提高了后期处理的效率。
This paper introduces the application of GPS PPS signal and the differential GPS instruments in the seismic exploration equipments. In order to generate seismic waves and acguire the reflected waves rigorous simultaneously, the over controlled crystals oscillator (OCXO) and phase-locked loop circuit (PLL) are applied in the specific applications. In order to make data acquisition more effective and links between data more stronger, it needs to array the equipments which have integrated GPS OEM. Under the help of differential GPS ,it is more accurate and strict to array the equipments, and we will operate the equipments more convenienty.
