摘要
提出了一种基于GPS定位技术和可视化程序开发工具的工程船舶动态导航系统。在简单介绍了差分GPS技术原理的基础上,给出了动态导航系统的结构模型。在上位导航软件的开发过程中,围绕定位数据的采集与坐标转换、实际大地坐标与图形显示坐标的对应关系等关键问题,提供了基于VB的简单可行的开发方案,实现了图形界面的实时多样化显示。经实际工程项目的检验,证明该系统操作简单、运行稳定、导航效果理想。
This paper proposes a dynamic navigation system for project ships on the basis of GPS＇s positioning technology and developing instruments of visual procedure. After briefly introducing the principle of difference division GPS technology, it provides the structure model of the dynamic navigation system. During the development course of the navigation software, there are such key problems as the gathering and changing of the data, the relationship of real earth coordinate, and graphical display coordinate. This paper offers some simple and feasible ways by using Visual Basic to realize real-time and diversified figure interface show. Actual inspection of project proves that it is simple, steady, and that it has ideal navigation results.
