摘　　要：介绍了GPS定位基本原理、常见定位方法及其发展历史,同时重点介绍了目前最为流行的连续运行GPS定位服务(CORS)的概念、基本原理、主要构成、实现模式及国内外现状,并通过CORS在大型水运、路桥工程中的具体案例应用介绍,总结CORS模式下GPS测量技术在大型项目的勘察设计、施工放样、检测维护各阶段无可替代的先进性,提出在将来大型工程中CORS其独特的高精度、全天候、多功能及多领域的应用前景。This paper introduces generally the basic principle of GPS,common positioning methods and the development history,describes in detail the concept,basic principle,composition and the realization mode of GPS based on the CORS,with the current situation both at home and abroad presented.Based on the application of CORS in large-scale water transportation and road bridge projects,this paper summarizes the unique advantages of GPS under the CORS mode in all the stages including the survey and design,construction layout,as well as the check and maintenance,and forecasts its application prospect in the large-scale projects which is characterized by the high accuracy,all-weather operation,multi-function and multi-field.
