摘要
分析了水下多种导航方式,提出了一种新的组合导航方式,即重力/惯性组合导航系统。介绍了它的研究背景和工作原理,并通过可视化仿真的方法模拟了整个导航过程。结果表明:重力匹配可以限制惯性导航系统的误差增长,实现长期水下高精度定位。
Several underwater navigation methods are analyzed, and a new integrated navigation method is put forward, i.e. integrated Gravity/Inertial Navigation System. The background and the principle of this system are introduced, and the whole process is simulated by a visual simulation manner. The experiment results demonstrate that the gravity matching methods can restrain the increase of error of the inertial navigation system, and acquire high accurate underwater positioning.
