| Abstract: | It discusses in detail the influence of some original elements such as operating distance,data synchronization,carrier's attitude and velocity of sound on the accuracy of GPS post-processing kinematic(PPK)hydrographic surveying without tidal observation.Then the mechanism of how the effect of turbulent waves on depth measurements is removed due to the application of GPS PPK is analyzed.And finally some quantitative demand on the observation and installation accuracy of attitude sensor and the measurement accuracy of relative position between GPS's aerial and depth-sounder transducer are suggested. |
