Abstract

A new position estimation method by using the signals from two automatic identification system (AIS) stations is proposed in this paper. The time of arrival (TOA) method is enhanced with the displacement correction, so that the vessel's position can be determined even for the situation where it can receive the signals from only two AIS base stations. Its implementation scheme based on the mathematical model is presented. Furthermore, performance analysis is carried out to illustrate the relation between the positioning errors and the displacement vector provided by auxiliary sensors. Finally, the positioning method is verified and its performance is evaluated by simulation. The results show that the positioning accuracy is acceptable.

摘要

本文提出了一种利用两个自动识别系统（AIS）基站信号的新的位置估计方法。通过位移校正增强了到达时间（TOA）方法，使得即使在船舶只能接收到来自两个AIS基站信号的情况下也能确定其位置。给出了基于数学模型的实现方案。此外，进行了性能分析以说明定位误差与辅助传感器提供的位移矢量之间的关系。最后，通过仿真对定位方法进行了验证并评估了其性能。结果表明定位精度是可接受的。
