GNSS RTK定位对中杆倾斜补偿技术及精度分析

GNSS RTK Positioning and Accuracy Analysis for the Oblique Compensation Technology

概述了GNSS RTK定位对中杆操作的有关问题,分析了倾斜补偿技术原理及其在实际定位中起到的作用,利用具备IMU对中杆倾斜补偿功能的徕卡GS18进行RTK倾斜定位实验,对定位效果进行了计算分析,结果表明高精度的倾斜补偿,能够克服在墙角、电线杆等需要进行偏心观测或是在沟渠、管线等难以进行普通RTK测量的环境下的测量困难,在保证精度的前提下,有效提高了测量工作效率。

Firstly,we outlined the related problems of GNSS RTK positioning for centering rod operation.And then,we discussed the principle of oblique compensation technology and its role in actual positioning.Finally,we carried out RTK positioning experiment on Leica GS18 ma-chine with IMU oblique compensation function for centering rod,and summarized and analyzed the positioning effect.The result shows that high-precision oblique compensation can overcome the measurement difficulties in the environment where eccentric observation is needed in cor-ners and telegraph poles,or it is difficult to carry out ordinary RTK measurement in ditches and pipelines,so that the measurement can be carried out more quickly.
