本文介绍一种便携式高精度水下高速运动体三维轨迹测量系统。文中叙述了定位解算数学模型、主要误差源、水下基阵校准及姿态修正方法。对距离模糊、多途干扰等问题亦作了分析。最后给出了部分湖上及海上试验结果。
This article describes a portable high-precision underwater high-speed three-dimensional trajectory trajectory measurement system. The paper describes the mathematical model of positioning solution, the main source of error, underwater alignment and attitude correction method. On the distance fuzzy, multi-way interference and other issues have also been analyzed. Finally, some lake and sea test results are given.
