将柔性坐标系引入经纬仪工业测量中，使其系统自定位不再受仪器整平误差和相对定向误差的影响。

Flexible coordinate system is introduced into theodolite industrial measurement, so there arent errors of instruments levelling and relative orientation in self locating of the system.

即使在平面声波条件不甚满足的情况下，其定向的相对误差也只有3.3%。

In some cases, although the condition of plane sound is not too satisfactory, the relative error of the azimuth is only 3.3%.
