摘要
：介绍了一个基于电子海图和GPS的船舶导航系统的结构、功能、主要技术特点及其实现原理。系统由GPS接收机、导航计算机、信号发射机、信号接收机、监视计算机及通信网络构成；包括海图显示、海图作业、航线设计、航路监视、航行再现以及打印五个功能模块；具有船形大小与实际船舶尺度相对应，船形运动平稳、兼容多种GPS数据格式，海图无缝拼接、一船运动多方监视、自动更换海图等特点。实验表明，该系统能够满足船舶引航的需要，使用它能够提高船舶航行的安全。
This paper Introduces the structure, functions, main technical features and the implementation principles of a ship navigation system based on electronic chart and GPS. The system consists of GPS receiving devices, navigation computers, signal sending devices, watching computers, a signal receiving device and a communication network comprises five function modules which are chart display, chart work, track design, track watching, navigation redisplay and print, etc, and has some features such as the scale of a ship sign is correspondent to that of the real ship, several GPS data formats can be used, the movement of ship sign is stable, charts are merged with no slots, several sites watch one moving ship, charts are selected and rambled through automatically, and so on. Experiments show that the system could satisfy the needs of ship navigations, and using this system could improve the safety of ship navigations.
