浅谈海底电缆声学定位数据在Gator系统中的处理流程

Introduction about the processing procedure of submarine cable acoustic positioning data in Gator system

声学定位技术具有高精度、高可靠性、高效率以及作业方式灵活等特点,其广泛应用于水下定位领域。在海底电缆地震勘探中,声学定位技术为确定水下检波器的具体位置提供了有效的解决方案。获得高质量的定位数据并且计算出检波器的实际位置,是处理地震资料的重要保证。本文介绍了海底电缆地震勘探中声学定位数据采集的一般过程,还介绍了Gator系统对于声学定位数据处理的流程和与其相应的质量控制节点,以及保证野外资料采集质量的意义。

Because acoustic positioning technology has the characteristics of high precision, high reliability, high efficiency and flexible operation mode, so it is widely used for underwater positioning. In the OBC seismic survey, the acoustic positioning technology provides an effective solution for identifying the specific location of the underwater geophone. Obtaining high-quality positioning data and calculating the exact position are very important to guarantee the seismic processing. This paper introduces the general process of acquiring the acoustic positioning data, the flow of data processing of Gator system, as well as the corresponding quality control measures for OBC survey.
