摘要
利用GPS载波相位差分测量技术,借助时间偏差改正、姿态改正、高程转换、信号处理和吃水改正,获得了测船处精密在航潮位。该方法已在几个GPS在航潮位测量实验中得到了验证,并取得了理想的结果。
A kind of new methed, which is GPS tidal level measurement, is presented for the determination of instantaneous tidal level at the vessel. The data processing procedure includes the time offset correction, attitude correction, quality control of GPS height; fusion of GPS height and heave, draft correction, and the filter of GPS tidal level. After these processing, precise tidal level at vessel is determined finally, and the new inethod is also praved by few experiments.
