摘要
随着海洋地震勘探以及GPS定位技术的高速发展,传统的海洋地震数据采集中的海上定位方式及导航数据处理技术逐渐成为了历史。然而,面对新、老海洋地震资料的连片处理,熟悉和掌握传统的海洋导航数据处理技术,对于提高观测数据的精度仍具有重要意义。为此本文介绍了传统的海洋定位技术、参考椭球体的建立和高斯投影方式,最后介绍了海上地震导航数据处理流程以及处理过程中应注意的几个问题。
Along with the rapid development of marine seismic exploration and GPS positioning technique, the traditional marine positioning way and naviga- tion data processing technique have gradually become history. However,in view of pieces-tied processing of new with legacy marine seismic data,familiar with and mastering the traditional marine navigation data processing techniques still have an important meaning for improving the precision of surveyed data. For that reason, the paper introduced traditional marine positioning technique,referential ellipsoidal build-up and Gauss projective way,finally, the paper introduced the marine seismic navigation data processing flow as well as the issues needing attention in processing.
