The utility model discloses a transmission tower space node positioner. Wherein, the device includes: laser rangefinder, universal cloud platform, electron compass handles the chip, handle the chip and receive the angle of elevation and the course angle that straight -line distance that laser rangefinder recorded and electron compass recorded, then output is by the space coordinate of survey node. The utility model provides a transmission tower space node positioner has solved in the correlation technique transmission tower and has measured the scheme and can't compromise measurement accuracy and problem easy and simple to handle, can be used to the space coordinate's of the crucial node of transmission tower pointwise location, still can be used to measure transmission tower overall structure's the deformation condition, and its institute surveys deformation data and can be used to the analysis of shaft tower running state, declares broken rod tower safe coefficient, simple and practical, and convenient to carry has improved measurement accuracy 0.
