摘要
为了检测多路径效应对实时动态测量方法的影响,笔者在大面积湖面、树林、高压线、观测视线与高大建筑物的不同高度角条件下进行了实时动态测量实验。使用GPS静态测量布置一些观测点,选出部分点作为已知点,并分别使用RTK和全站仪进行观测其他点。对两者测出的数据进行比较和分析后,发现这些地形、地物对RTK测量工作存在影响,并提出了相关建议。
In order to detect the influence of multipath effects on the real-time kinematic （RTK） measurement methods, the authors made a real-time dynamic measurement experiment on broad lakes, forests, high-tension lines, observation sight and tall buildings under the condition of different elevation angles. The authors first used GPS static measurement to set some observation points and then chose some points as known points, and utilized RTK and total station instrument to observe other points. A comparative analysis of the measured data from the two instruments shows that the terrain affects the measurement work. The authors therefore made some recommendations.
