针对目前广泛应用的卫星导航系统存在的易受干扰等局限性,提出了将区域无线电定位系统应用于港口引航作业的设想。首先,介绍区域无线电定位系统的系统组成和工作原理,依据双曲线定位原理建立了区域无线电定位系统的定位解算数学模型,通过计算几何精度因子推算出区域无线电定位系统的定位误差。最后经过仿真计算,验证了在港口引航作业应用区域无线电定位系统可提高船舶定位精度。
In view of the limitations of the currently widely used satellite navigation system such as the susceptibility to interference, a tentative plan for applying the regional radio positioning system to port piloting operations is proposed. Firstly, the system composition and working principle of regional radio positioning system are introduced. Based on the hyperbolic positioning principle, a mathematical model of positioning and solving of the regional radio positioning system is established. The positioning error of the regional radio positioning system is deduced by calculating the geometric accuracy factor. Finally, after the simulation calculation, it is verified that the radio positioning system in the port piloting application area can improve the ship positioning accuracy.
