摘要：
In order to improve the precision and improve the monitoring system of surface subsidence, the monitoring results are more accurate. Using GPS (Global Positioning System) technology and traditional leveling method, combined with the characteristics of surface subsidence monitoring, GPS leveling is carried out. According to the principles of various fitting models and the characteristics of different fitting models, a step-by-step hybrid model is proposed, and its practicability is verified. The results show that the fitting precision of the step-by-step hybrid model improved by GPS technology is higher than that of the traditional method. It provides a new idea for the application of GPS technology in the monitoring of surface subsidence, and has a reference value for the research and design of fitting model. measurement; GPS elevation fitting model
