Based on a brief review of coastal erosion monitoring practices both abroad and at home, we made an introduction to the principles and operation of the GNSS-RTK technology in this paper. All the results of the monitoring data with different topography are described and evaluated. Comparison is also made with other methods. The results prove that GNSS-RTK technology is an appropriate method to achieve high-precision coastal zone erosion monitoring.
