载波相位差分技术在山地道路测量中的应用浅谈

Elementary Discussion on Application of Carrier Phase Difference Technology in Measurement of Mountainous Road

在野外实时测量中,载波相位差分技术具有实时性好、精度高、速度快等优点,在道路勘测与放样方面与常规测量相比具有明显的优势。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探讨其在道路工程测量中中桩放线与纵横断面测量的应用。

In the field real-time measurement, the carrier phase difference technology has the advantages of good real-time quality, high accuracy and fast speed. In aspects of road survey and lofting, this technology has more obvious advantages than the normal survey. The article further discusses the application of GPS-RTK technology in pile lofting and vertical section measurement of road engineering measurement from the aspects of software and hardware environment, operation mode, data processing, the technical features and accuracy influence.
