在地勘测量中应用RTK技术

RTK technology in geological exploration and survey

传统光学仪器测量需要测量点之间通视,数据需要手工记录和进行繁琐的后处理。RTK技术将GPS接收机、现场手持计算机和无线电数据链相结合,实时提供cm级测量精度,可大大提高工作效率,减轻劳动强度。它由基准站、流动站和数据处理系统组成。在基准站安置GPS接收机,对GPS卫星进行连续观测,将观测数据通过无线电传输设备实时地发送给用户观测站。GPS接收机在接收卫星信号的同时接收基准站传输的观测数据,实时地计算并显示用户站的三维坐标及其精度。RTK技术可以替代常规测量为地质勘查工作快速提供可靠、高精度的测量成果。

The traditional optical instrument survey requires surveying points could be seen each other, the survey data should be recorded manually and processed later, RTK technology combines GPS receiver, spot handhold computer with radio data chain, and provides centimeter-precision, which can improve efficiency greatly and lighten working intension. RTK consist of reference station, roving station and data processing system. Installing a GPS receiver on the reference station and observing GPS satellites constantly, the observation data from reference station while receive the satellite signal, and compute and display the user station's 3D coordinate and their precision. RTK technology can provide reliable and high precision survey production for geological exploration substitute for general survey method rapidly.
