The invention discloses a side-scan sonar fixing and mounting device and method based on an integrated navigation system, and particularly relates to marine surveying and mapping, the side-scan sonar fixing and mounting device comprises a propeller, a flange piece is welded to the propeller, and a support rod is mounted on the flange piece; the mounting platform is fixedly provided with a first shroud ring side petal, the first shroud ring side petal and the second shroud ring side petal are hooped on the support rod, and an IMU (Inertial Measurement Unit) is fixedly mounted on the mounting platform; a mounting groove table is welded to the end of the support rod, and a GNSS antenna disc is fixedly mounted at one end of the mounting plate. A high-precision integrated navigation system formed by combining an IMU (inertial measurement unit) and a GNSS (global navigation satellite system) antenna disc is utilized to provide positioning, orientation and attitude data and 1pps time synchronization data, heading and attitude data and side-scan sonar original data are spliced, and the positioning, heading and attitude of a tow fish are corrected, so that a high-precision side-scan sonar image map is generated.
本发明公开了一种基于组合导航系统的侧扫声呐固定安装装置及方法,具体涉及海洋测绘,包括推进器,所述推进器上焊接有法兰件,所述法兰件上安装有支架杆;还包括固定安装有第一箍环侧瓣的安装平台以及第二箍环侧瓣,所述第一箍环侧瓣与所述第二箍环侧瓣抱箍于所述支架杆上,所述安装平台上固定安装有IMU;所述支架杆的端部焊接有安装槽台,还包括安装板,所述安装板一端固定安装有GNSS天线盘。该发明利用IMU和GNSS天线盘结合组成的高精度组合导航系统,提供定位、定向、姿态数据和1pps时间同步数据,将艏向、姿态数据与侧扫声呐原始数据拼合,改正拖鱼定位,艏向及姿态,进而生成高精度的侧扫声呐影像图。
