Abstract: A surveying system can include a surveying instrument, a control system, a tilt measuring system, a levelling unit, a camera system, and a second distance meter, wherein the control system is configured for obtaining an image position of a captured image, adjusting a tilt status until a first tilt status is obtained, the second distance meter aiming onto the location on the ground in the first tilt status, determining the first tilt status, effecting the second distance meter to measure a distance to the location on the ground, effecting a first angle encoder to measure a rotatory position of a support unit, effecting the levelling unit to adjust the tilt status, and calibrating a preconfigured centre point based on the distance to the location on the ground, a deviation between the first tilt status and the second tilt status, and/or the rotatory position of the support unit.

Abstract: A distance measuring device comprising an optical transmitter channel for transmitting laser light along a transmitter path and an optical reception channel for receiving laser light along a reception path. At least one optical element including a glass part with a coated surface is positioned in the optical transmitter channel or in the optical reception channel. The glass part includes a glass pane with a thickness below 0.3 mm, with a peripheral edge and with a coating on at least one of the two surfaces, and a ring element. The glass pane is adhesively connected to an end face of the ring element. This distance measuring device shows reduced measuring artefacts and/or reduced optical aberration effects and/or a reduced weight.

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.
