摘　　要：随着科学技术的不断发展,人们对水下地形测量的精度需求越来越高。无人船搭载单波束测深仪通过集成计算机与测量设备实施水下地形测量,已逐渐成为内陆浅水区域水下测量的主要技术手段。本文通过与传统水下测量模式进行对比,分析GPS-RTK在无验潮模式下进行水下测量的原理及优势,并对其可靠性进行了验证,阐述了如何更加有效地将无人船测量技术应用到实际生产当中。With the continuous development of science and technology,there is an increasing demand for the accuracy of underwater topography.Unmanned surface vessel(USV)equipped with single-beam echo sounder to carry out underwater topographic survey through integrated computer and measuring equipment has gradually become the main technical way of underwater survey in inland shallow water areas.This article compares with the traditional underwater measurement mode,analyzes the principle and advantages of GPS-RTK in underwater measurement in the non-tide test mode,verifies its reliability,and explains how to apply the USV measurement technology to actual production more effectively.
