| Abstract: | 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. |
