摘　　要：虽然近年来随着科学技术的发展及市场的需求,无人机航测技术在测绘行业中逐步得到广泛应用,但GPSRTK技术凭借其操作简便、测量时间短、精度高、无需通视等优点,依然是各种常规工程测量作业中不可缺少的重要测量手段。本文以某项目地形测绘为例,详细介绍GPS-RTK技术测量中所包含的电台模式与CORS模式这两种模式的工作原理,并通过野外数据采集实例对比两种模式的优缺点,提出两种工作模式在野外作业的适用建议。Although in recent years,with the development of science and technology and the demand of the market,UAV aerial survey technology has gradually been widely used in the surveying and mapping industry,GPS-RTK technology,with its advantages of simple operation,short measurement time,high accuracy and no intervisibility,is still an indispensable and important measurement means in various conventional engineering surveying operations.Taking the topographic mapping of a project as an example,this paper introduces in detail the working principles of the radio mode and CORS mode included in the GPS-RTK technical survey,compares the advantages and disadvantages of the two modes through field data acquisition examples,and puts forward suggestions for the application of the two working modes in field operations.
