Abstract: This study addresses the limitations of traditional static calibration methods for seismic vessel navigation equipment. By using GNSS-RTK technology with RTK and PPP (Precise Point Positioning) single-point positioning processing methods, dynamic calibration of navigation equipment can be achieved. Through the analysis of the quality of single dynamic calibration data and comparison with conventional correction data, it is concluded that the dynamic calibration technique is of the characteristics of high accuracy and stability. Additionally, this technology has the advantage of not being affected by time, location, and weather, and can effectively avoid human errors in practical applications. Compared with conventional static correction, it saves operation time and costs, and makes this technology a certain promotion value.
