相对估计的舰船组合导航定位算法研究及性能分析

Research and performance analysis of integrated navigation and positioning algorithm of ship based on relative estimation

舰船信息化的程度在不断的提高,多传感器网络规模在变大、结构变得复杂,通过多信息的融合来获取更加准确的船舶定位,能够有效的避免各种海上事故。本文在舰船组合导航系统的基础上,应用相对估计的方式开展舰船导航定位研究,最后进行仿真实验。通过实验对比可看出,本文算法精度高、误差小,具有更高的实用性。

The degree of ship information is increasing. The size of the sensor network is becoming larger and the structure becomes more complex. It can effectively avoid all kinds of maritime accidents by the fusion of multi information to obtain more accurate positioning of the ship. In this paper, based on the integrated navigation system of ships, the relative estimation method was applied to the ship navigation and positioning. Finally, the simulation experiments were carried out.The experimental results showed that the algorithm had high accuracy, small error and high practicability.
