GPS RTK在图根控制测量中的应用

The Application of GPS RTK in Mapping Control Survey

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,因其作业效率高、没有误差积累、作业自动化程度高、操作简便、数据处理能力强和需要人员少等优点在各行各业中得以广泛应用。本文通过工作实践,着重介绍GPS RTK技术在城市大比例尺地形图测绘中图根控制测量部分的应用,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,提出来与大家共同探讨。

GPS RTK technique adopts cartier phase real -time kinematics differential technology for relative positioning. It has some advantages, such as high working efficiency, without accumulation of errors, high working automatic level, simple manipulation, strong capability in data processing and fewer personnel needed, etc. Therefore, it is widely applied in various industries. 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.
