摘　　要：为充分利用沿岸水域导航定位物标多的特点,依据传统陆标定位原理,引入磁方位传感器、高分辨率图像传感器等现代技术手段,设计基于电子海图显示与信息系统(ECDIS)的改进型陆标定位系统。所设计的定位系统能将对沿海物标进行观测信息直接传递给ECDIS,通过所建立船位求解模型对获得的信息进行分析处理,直接在ECDIS上显示船位。经过沿海水域的海上实船实验,所建立的定位系统能较快地获得具有较高精度的船位,可成为小型船舶沿岸航行较为有效的定位系统。Fully using those terrestrial marks alongside offshore and according to the principle of traditional terrestrial fixing, drawing into magnetic direction sensor, high resolution picture sensor and other modern technology, to set up an improved terrestrial fixing system based on ECDIS. The improved fixing system transfer observation information of terrestrial marks, deal with those observation information by using the built vessel position counting model and display fixing position on the ECDIS directly. The real vessel test on the coastal water area showed the fixing system can provide high-accuracy position quickly. It can be an effective position fixing system of small-scale vessels navigating alongside coastal water.
