针对海洋工程测量作业工程船只自身的特殊性,导致对超短基线定位系统无法采用常规的动态校准方法这一问题,该文根据天文方位测量原理,结合全站仪高精度的角度测量和GPS定位及授时测量,对超短基线定位系统的发射接收机参考指向与船体中轴线之间的水平角度偏差进行静态校准。通过编制相应的校准程序,结合在海洋工程中的海底管线铺设中的应用进行验证,测量分析结果表明,超短基线定位系统静态校准方法满足水下导航定位施工作业的精度要求,取得了良好的实施效果。
In view of the particularity of offshore engineering surveying vessel itself, the conventional dynamic calibration method can not be applied to the ultra-short baseline positioning system. According to the principle of astronomical azimuth measurement, combined with the high-precision total station angle measurement and GPS positioning And timing measurements to statically calibrate the horizontal angle deviation between the reference point of the transceiver of the ultra-short baseline positioning system and the central axis of the hull. Through the preparation of the corresponding calibration procedure and the application in the submarine pipeline laying in marine engineering, the results of the measurement and analysis show that the static calibration method of the ultra-short baseline positioning system meets the precision requirements of underwater navigation and positioning work and a good Implementation Effect.
