| Abstract: | This paper analyzes the characteristics of the observational data about the marine seismic cable trawl nodes. The high-precision and near real-time navigation positioning information of marine seismic cable trawl node is gained by three-dimensional adjustment methods and the variable bandwidth square root method. The problem of accuracy and computational speed about the cable trawl navigation and positioning is solved in data processing. |
