摘　　要：相比传统的跨河水准测量,GPS跨河水准测量有着明显的技术和效率优势。本文介绍了GPS水准测量的基本原理;结合跨河水准测量实例,阐述了GPS跨河水准测量的设计、施测及数据处理方法,并提出了提高测量精度的建议和方法。数据处理结果显示,在地势变化不大的区域,GPS水准测量方法可以取代传统跨水准测量用来进行二等跨河水准测量。Compared to traditional river-crossing leveling,GPS river-crossing leveling has a obvious advantage of technology and efficiency.This paper describes the basic principles of GPS leveling,and introduces design,measuring and data processing facilities of GPS river-crossing leveling with leveling instance.It eventually makes recommendations and method to improve accuracy of measurement.The Data processing result shows that GPS river-crossing leveling can replace the traditional measurement used for Second-Class river-crossing leveling in flat areas.
