This technology can do repetitionmeasurement of well bore track, determine drilling direction and window cutting direction of sidetrack well and so on.
该技术可用于井身轨迹复测、钻井定向和侧钻井开窗定向等。

Line repetitionmeasurement is on important link in transmission line construction, which directs the localization of poles and towers, directionality and linearity of lines.
线路复测为线路杆塔的定位、线路的方向性、直线性等提供依据，是输电线路施工的重要环节。
