摘　　要：近年来,基于CORS模式下的GPSRTK测量技术已得到广泛应用,逐步替代了基于电台模式下的GPSRTK测量技术,但在一些水利工程测量中,由于现场树木较多、CORS信号较差,仍需用到电台模式下的GPSRTK测量技术。本文通过对1∶500比例尺地形图测绘项目的生产实验,对两种模式下获取点坐标的方法进行了探讨。In recent years,GPSRTK measurement technology based on CORS mode has been widely used,gradually replacing GPSRTK measurement technology based on radio mode.However,in some water engineering survey,due to more trees on site and poor CORS signal,GPSRTK measurement technology under radio mode is still needed.Based on the production experiment of 1:500 scale topographic map surveying and mapping project,this paper discusses the methods of obtaining point coordinates in two modes.

关 键 词：工程测量 GPSRTK CORS 点位坐标
