Abstract
An industrial or geodetic surveying device with a scan functionality including an alidade rotating about a standing axis and a telescope unit with a beam exit for a laser measuring beam. The telescope unit is mounted on the alidade and is movable in a tilting motion about an elevation axis substantially orthogonal to the standing axis. The scan functionality comprises a scan sequence with an angular velocity of the alidade around the standing axis, wherein during the scan sequence the alidade is in a continuous revolving motion with mainly constant angular velocity about the standing axis, and the angular velocity of the alidade is faster than half of the angular velocity of the tilting motion of the telescope unit about the elevation axis.
