摘要
RTK技术的出现,使得野外实时测量精度达到cm级别,RTK测量具有实时性好、精度高、速度快等优点,是常规测量所无法比拟的,因此,RTK-GPS已经作为快速采集数据与定位的有效工具。本文主要从RTK技术在测量中的工作模式、数据链的结构、技术特点、RTK作业步骤、RTK成果精度影响因素等方面,进一步讨论其在实际道路测量中的控制测量、线路勘测、中线测量、施工放样等方面的应用。
The emergence of RTK technology, the RTK-GPS positioning can be achieved cm level precision in the field. RTK survey have advantages of good real-time quality ,high accuracy ,quick speed .The normal survey can′t be compared with RTK survey ,for the reasons ,it has become an effective tool in the rapid data collecting and positioning .In this paper it was recounted the development of the RTK-GPS including measurement models, data chain structures and the technology characteristics, RTK work process, RTK production precision effect. Its application in the concrete highway survey work such as control , road and layout surveying was discussed.
