RTK技术在道路测量中的应用

在野外测量实时测量中，RTK的精度可以达到厘米级，且具有实时性好，速度快等优点。在公路勘测和放样方面与常规测量相比具有明显优势，因此，GPS—RTK已经成为道路工程中快速采集数据与定位的有效工具。主要从GPS—RTK技术的软、硬件环境，工作模式，数据处理，技术特点及精度影响等方面，进一步讨论其在实际道路测量中的控制测量、线路勘测、中线及纵、横断面施工放样等方面的应用。

Application of RTK Technology in the Road Survey

The precision of the RTK-GPS with the advantages of good real-time quality and high-speed could amount to centimeter level in the real-time survey of the field, In aspects of road survey and lay-out, RTK survey had more obvious advantages than the normal survey. Therefore it had become an effective tool in rapidly collecting data and positioning in the road engineering. This paper discussed the application of the RTK-GPS in control survey, line survey and layout in the highway and an real-survev any further from the consideration of the aspects of software and hardware environment, mode of operation, data processing, the technical features and RTK-GPS precision influence.
