Assignee: HEXAGON TECHNOLOGY CENTER GMBH
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A surveying device comprising:
a radiation source for generation of a distance measurement beam;
a base defining a vertical axis;
a support defining a tilt axis, the support being arranged on the base and rotatable relative to the base about the vertical axis as a first axis of rotation;
a targeting unit carried by the support, the targeting unit being arranged rotatable relative to the support about the tilt axis as a second axis of rotation, for emitting the distance measurement beam in an emission direction into free space, the emission direction being variable with respect to the vertical axis and the tilt axis;
a first angle encoder for measuring the respective relative position of the support with respect to the vertical axis;
a second angle encoder for measuring the respective relative position of the targeting unit with respect to the tilt axis;
a beam deflection element situated in the targeting unit and being rotatable about a deflection axis as a third axis of rotation, the deflection axis being congruent to the tilt axis and the beam deflection element being arranged in such a way in a distance measurement beam path that the emission direction can be varied with respect to the deflection axis; and
a third angle encoder for measuring the respective relative position of the beam deflection element with respect to the deflection axis.
