摘要
采用载波相位实时动态差分技术进行相对定位的GPS RTK技术,能够在野外实时得到厘米级定位精度,将其用于工程放样、地形(籍)测图及某些控制测量,可以极大地提高作业效率。本文着重介绍GPS RTK技术在大比例尺地形图测绘中在图根控制测量方面的应用,通过工程实例与传统的控制测量方法进行作业过程、工作效率及精度方面的比较,得出两者之间的优缺点,对工程实践具有一定的参考价值。
GPS RTK technique adopts carrier phase real -time kinematics differential technology for relative positioning. It can real - time acquire coordinates in centimeter level in the field. It is also able to improve working efficiency with the application in engineering setting, topographic mapping and control survey. This paper mainly introduced the application of GPS RTK technique in mapping control survey of large - scale topographic surveying and mapping. Based on the comparison of working procedure, efficiency and accuracy between using GPS RTK technique and traditional control survey in practical example, it put forward the advantages and disadvantages of the two methods. It is valuable for engineering practice.
