摘要
根据一体化姿态传感器的特点和多波束水深点计算的实际需要,重点讨论了多波束探头安装偏差的处理,提出了把综合偏差输入姿态传感器,利用其偏差校准处理功能,实现多波束探头坐标系的横摇、纵摇和航向的直接输出,简化数据处理提高作业效率的设想;给出了姿态传感器安装偏差与多波束探头安装偏差进行合并获得综合偏差的方法。
According to the feature of the motion sensor and the necessity of the calculation of multibeam sounding points, this paper mainly discusses the correction of the installation offset of multibeam transducer. By inputting all the installation offsets of the multibeam transducer to the motion sensor. The motion sensor can output all the pitch, roll and heading values in the reference framework of the multibeam transducer using it＇ s total offset correction function. This method simplifies data processing and enhances the efficiency. This paper gives a method to calculate the total offset caused by the installation offsets of both the motion sensor and the multibeam transducer.
