I摘 要随着卫星定位系统的作用越来越深入，各种应用卫星的定位系统应运而生，船舶航行对卫星定位的依赖已经无法分开。本文在 GPS 导航技术的发展、原理研究的基础上，主要探讨了GPS 在航海领域中的应用。在分析三个航海案例的基础上，通过具体案例对比分析从而得出上述传统导航技术与 GPS 技术结合的效果，并进一步设计了基于 GPS 的海上搜救方案。分析表明，GPS技术与传统航海导航技术的结合，有利于提高船舶航行安全。 关键字：GPS，雷达，卫星定位AbstractIIWith the deepening of the satellite positioning system and its functions, various satellite positioning systems have come into being.On the basis of the development and principle of GPS navigation technology, this paper mainly discusses the application of GPS in navigation field. Based on the analysis of electronic chart, radar and other traditional navigation technologies, the effect of the combination of the traditional navigation technology and GPS technology is analyzed through the comparison of specific cases, and the advantages of the combination of GPS and search and rescue beacon, black box and Marine fishery detector are further discussed. The analysis shows that the combination of GPS technology and traditional navigation technology is helpful to improve the navigation safety of ships.Key words：GPS，Radar，Electronic chart目 录摘 要.....................................................................IAbstract.................................................................II第 1 章：引言..............................................................11.1 课题意义及研究背景.................................................11.2 GPS 在航海领域应用现状.............................................11.3 论文组织安排.......................................................4第 2 章 案例分析...........................................................52.1 案例一.....................................................
