摘要
在输电线路施工中,要进行中心桩复测和补桩工作。当环境条件不好无法通视时,就不能用传统光学仪器进行测量,而借助GPS测量技术能方便、快速、准确地完成测量工作。选用2台GPS双频机构成动态RTK测量系统,其测量精度可以达到cm级水平,完全能满足测量规范要求,可广泛应用于直线塔和转角塔的中心桩测量定位。
During construction of transmission lines it is necessary to re - check the central pile and supplement the piles. While the environmental conditions are not enough for vision, it is impossible to use the traditional optical instrument for measurement. But by means of GPS measuring technique the job can be done conveniently, quickly and correctly. With a dynamic RTK measuring system consisting of 2 GPS double - frequency mechanism the measuring accuracy can be up to cm level and meet the requirements of the codes completely. The system is widely suitable for measurement and position of the central piles used for suspension and angle towers.
