Localization accuracy is crucial for achieving reliable location tagging for underwater missions. However, the accuracy of conventional range-free localization schemes with a mobile beacon is distorted by ship dynamics (i.e., pitch, roll, and heave) over oceanic conditions, and the schemes suffer from two uncertainties: beacon point and geometric shape uncertainties. To reduce the effects of these uncertainties, we herein propose LMB-MC, a novel range-free localization scheme. LMB-MC compensates beacon point errors and employs an accurate geometric model instead of an unconditional circle-shaped model. Furthermore, we adopted real-world motion measurements from an operating ship and used motion data to support diverse simulation settings (i.e., Douglas sea scales). Result of extensive simulation studies verified that LMB-MC provided improved accuracy and reliability compared to the existing solutions in the considered oceanic environments.

通过水下传感器网络中的运动补偿使用移动信标进行无距离定位

定位精度对于实现水下任务的可靠位置标记至关重要。然而，具有移动信标的传统无距离定位方案的准确性会受到海洋条件下船舶动力学（即俯仰、横摇和升沉）的影响，并且该方案存在两个不确定性：信标点和几何形状不确定性。为了减少这些不确定性的影响，我们在此提出 LMB-MC，一种新型的无距离定位方案。LMB-MC 补偿信标点误差并采用精确的几何模型而不是无条件的圆形模型。此外，我们采用了来自运营船舶的真实世界运动测量值，并使用运动数据来支持不同的模拟设置（即道格拉斯海标）。
