船舶在狭水道中运用GPS、ARPA、ECDIS定位技术研究

Research on GPS,ARPA and ECDIS Fixing Technology in a Narrow Channel

船舶在狭水道或进出港航道航行时,为确保船舶航行在预定的航迹线上,传统的定位与导航方法大多是利用助航标志。本文基于GPS、船用雷达(ARPA)和电子海图(ECDIS)等航海仪器与设备功能特点,就船舶运用GPS、船用雷达和电子海图以确定船舶在狭水道航行的航迹线方法作了研究,并就方法的运用提出了相应的注意事项。

When navigating in a narrow channel or a fairway in a port, vessels usually fix their positions by means of navigational aids so that they can navigate in the planned route. Based on funtional characteristics of GPS, Radar and electronic charts, by means of an example of proceeding in a one-way fairway in a port, the paper carried out specialized research on how to ascertain a path line in a narrow channel or one-way fairway by making use of GPS fixing, Radar fixing and electronic charts fixing, and presented points for attention with regard to ascertaining the path line.
