摘要
RTK技术的普遍应用,大幅提高了野外测绘作业的效率。随着中国北斗卫星导航系统信号的加入,全天可用卫星数量远超RTK测量要求,因而其服务可用性得到了显著提高。文章基于兼容GPS、GLONASS和BDS信号的珠海北斗CORS,实测获取了通过区域似大地水准面内插改正的RTK高程测量数据,将其与对应的四等水准测量成果进行对比。结果表明:RTK高程测量成果与四等水准测量成果的精度一致性较好。
Widespread the application of RTK technology, the efficiency of field surveying and mapping work has been greatly raised. With the start using of BDS, the number of available satellites is far more than that of the RTK meas- urement requirements, thus its service availability is improved significantly. Based on ZHBDCORS combining with GPS, GLONASS and BDS signals, the RTK measurement data obtained by interpolating correction of area quasi-geoid, has been compared with the corresponding fourth-order leveling data. The result shows that the accuracy of RTK elevation measurement data is equal to that of fourth-order leveling data.
