摘　　要：针对传统物探船导航设备静态校正方法的局限性问题,利用GNSS-RTK(Global Navigation Satellite System-Real-Time Kinematic)技术,使用RTK(Real-Time Kinematic)处理方法和PPP(Precise Point Positioning)单点定位处理方法,可以实现物探船导航设备动态校正。通过对单次动态校正数据质量的分析以及与常规校正数据的对比,得出动态校正技术具有高精度、高稳定性的特点。此外,该技术还具有不受时间、地点和天气影响的优势,在实际应用中能有效规避人为误差,对比常规静态校正,节约作业时间及成本,使得该技术具有一定的推广价值。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.
