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.

Abstract: A target of a geodetic system based on global and local identification references. The target comprises a light emitter (LE) for emitting n predetermined modulated light patterns (MLPs) permanently assigned to one of m (m>n) global identification reference (GIR). The target transmits or receives data based on the assigned GIR. The geodetic system further comprises a geodetic surveying instrument comprising an optical sensor (OS) receives the MLPs and digitizes them using a fast sampling analogue-to-digital converter (ADC). A computing system selects one of the targets or receives a selection of the at least one target assigned to a selected GIR. One of n local identification references (LIRs) is temporarily assigned to the selected GIR. The light emitter of the selected target is directed to emit an MLP corresponding with the assigned LIR. Thus, by detection of the assigned LIR, the selected target is identified.

Abstract: A method comprising: setting up a stationary surveying device at a first known positioning in a surrounding area of the object; retrieving from a memory a set of object points of an object to be surveyed and/or to be marked; surveying and/or marking from a first positioning object points of the set of object points that can be surveyed and/or can be marked from the first positioning by means of the free beam, on the basis of a target direction; ascertaining missing object points of a set of object points; relocating the surveying device to a second, unknown positioning in the surrounding area of the object; automatically determining a second positioning by the surveying device on the basis of the knowledge of the first positioning, so that the second positioning is known; surveying and/or marking missing object points by means of the free beam from the second positioning.

Abstract: A coordinate measuring and/or stake out device can be designed for being hand-held (one-handed), free carriage and movement by a user. A position giving means is for determination of an actual translational position of the device using an external position reference and an orientation giving means for determination of an actual rotational position of the device, such that the actual position of the device with respect to all six degrees of freedom of the device can be determined. A radiation source is for generation of a radiation beam as measuring and/or marking beam for measuring and/or visually marking of an object point. A beam steerer is for automatic steering of an alignment of the beam, whereby the beam which differ in the manner of automatic steering the beam alignment.

Abstract: A surveying pole system comprising a surveying pole including two telescopic sections for providing length adjustability. At a first end of the surveying pole, a pointing tip is disposed for positioning on a target point of the environment. At a second end, a length reference point is disposed. The surveying pole also includes a locking mechanism for locking the length adjustability in respective lock-in positions. Each of the lock-in positions provides a corresponding distance between the pointing tip and the length reference point. A plurality of coded identifiers have a predetermined code associated with one of the lock-in positions. The surveying pole also includes a coded-identifier reader for reading the code of a respective coded identifier associated with the respective lock-in position, a communication device configured for transmitting a signal to a surveying instrument, wherein the signal is based at least on the read code.
