Abstract:Along with the rapid development of marineseismic exploration and GPS positioning technique,tion data processing technique have gradually be-come history. However, in view of pieces-tied pro-cessing of new with legacy marine seismic data, fa-miliar with and mastering the traditional marinenavigation data processing techniques still have animportant meaning for improving the precision ofsurveyed data. For that reason, the paper intro-duced traditional marine positioning technique, ref-erential ellipsoidal build-up and Gauss projectiveway, finally. the paper introduced the marine seis-mic navigation data processing flow as well as theissues needing attention in processing.
