摘要
为解决公路工程测量过程中测量精度问题,本文结合某地区开展了以载波相位观测量的GPS精度计算,分析了GPS以载波相位观测量为处理对象的静态相对定位(RTK)技术在道路测量的应用。基于连续运行基准站(COBS)的GPS点全局控制检测站,通过在某一地区设定各未知点,采用不同基准站进行了系统的精度测量实验,测量精度高程分布和水平分量均保持在2 cm以内,满足工程测量需求。结构该区域道路工程实例,对CORS框架的高精度GPS公路测量中的应用进行了大量数据对比分析,从获得的数据结果中表明该方法在道路测量中具备高GPS定位精度。
To solve the problem of highway engineering survey in the process of measuring precision,this paper conducted a region is in carrier phase observations of GPS accuracy calculation,analyzed the GPS carrier phase observation quantity as the object of the static relative positioning(RTK)technology in road measurement applications.Based on continuous operating reference station(COBS)global control testing station,GPS point by setting all unknown points in a certain region,the different base station is used for system,the precision of the measurement accuracy of measurement vertical distribution and horizontal component are kept within 2 cm,meet the demand of engineering measurement.Structure of the region road engineering as an example,the application of high precision GPS highway surveying of CORS framework for a large number of data analysis,the data obtained from the results show that the method in road measurement with high precision of GPS positioning.
