基于轨迹偏差的动态定位精度评定方法

A Method of Dynamic Positioning Accuracy Assessment Based on Trajectory Bias

针对利用高精度全站仪对GPS动态定位精度评定时遇到的测量时间标志不准确的问题,提出了一种基于轨迹偏差的动态定位精度评定方法。从最简单的GPS测量轨迹和全站仪测量轨迹平行的情况开始证明,进而对现实中的曲线轨迹进行了简化证明,并给出了该方法的实施步骤。最后通过实验验证了该方法的有效性。

In order to solve the problem of inaccurate measurement time flag,when assessed the dynamic positioning accuracy of GPS using high-precision total station,a new method of dynamic positioning accuracy assessment based on trajectory Bias was proposed.First,when the trajectory of GPS and total station was parallel,the proposed method was proved,and when the trajectory was curve,it was proved simply.And then the implementation steps of the method was proposed.Finally,the experiment result showed that the proposed method was effective.
