摘　　要：在近海、湖泊等水下地形的测量中 ,GPS与测深仪联用越来越广泛 ,GPS在水下地形测量中的定位精度受到诸多因素的影响 ,如GPS的安装、采集数据的后处理等。本文从安装方式。In the underwater topography surveying near sea or lake, GPS is widely used with the echo sounder,the positioning precision of GPS in the underwater topography surveying is impacted by such factors as GPS installment, post processing of captured data. Installment mode, reliability analysis of captured data and all kinds of real-time diverse modify are discussed in the paper.
