摘　　要：分析了海上地震探测电缆拖网节点观测数据的特点,利用三维平差方法,采取变带宽平方根法等数据处理策略,获得高精度、准实时的海上地震探测电缆拖网节点导航定位信息,从数据处理方面解决了电缆拖网导航定位精度和计算速度的问题。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.
