Using RTK three-dimensional bathymetric technology to model the dynamic tidal level of multi-beam Bathymetric system . this method is applied to the dynamic tidal level correction of Multi-beam Bathymetric system. Two reduction algorithms and seven discrete methods are compared and analyzed. It is found that if the discretization process is realized by RTK three-dimensional bathymetric technology, it will be simplified. It can be realized by RTK three-dimensional bathymetry technology, and the simplification effect of observation variables is better. The validity of prediction is validated by RTK three-dimensional bathymetry technology, and the validity is better than that of hierarchical regression method. Finally, the experimental results show that RTK used in dynamic tidal level correction of multi-beam bathymetry system is effective. Three-dimensional bathymetry is very effective.
