Abstract: A surveying device for determining the position of a target, comprising a means for orienting a target axis of the surveying device towards the target point, an angle-measuring functionality for the highly precise detection of the orientation of the target axis, and evaluation means for data storage, a height measuring system for determining a height of the surveying device above the ground by means of triangulation, wherein the height measuring system comprises at least one laser plummet for emitting a laser beam along a standing axis of the surveying device onto a ground point, and a detection unit comprising a line sensor for detecting a diffuse backscattering of the laser beam, and wherein the height measuring system for determining a height of the surveying device above the ground point is designed based on a position of the diffuse backscattering on the line sensor.
