摘    要:在物探0BC勘探施工中,测量工作一般只能提供接收线上检波点瞬间离开定位船的坐标,为了准确得到沉到海底的接收线检波点的坐标,需要对检波点进行重新测量,通过二次定位得到的检波点坐标为地震资料的解析提供了可靠的保证.本文介绍了二次定位系统的硬件组成、工作原理和在OBc勘探中的使用方法及注意事项.

Abstract:During operation of geophysical OBC exploration, measurement work generally only provides the coordinates that the receiver points on receiver line depart from positioning boat instantaneously, in order to get the coordinates of receiver points on receiver line sunk down the sea bottom accurately, it should again carry out the measurement of receiver points. The coordinates of receiver points got by secondary positioning provide reliable guarantee for inter-pretation of seismic data. The paper introduced the hardware composition, work principle of secondary positioning system and its application method in OBC exploration as well as matters needing attention.
Keywords:transducer  transponder  programmer  OBC  secondary positioning
