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 and to a secondary sensor unit which is attachable to the surveying pole. A reflector and/or GNSS receiver attachable to the surveying pole can be attached independently of whether or not the secondary sensor unit is attached to the surveying pole. A distance between the reflector and/or GNSS receiver and a pole tip is also independent of whether or not the secondary sensor unit is attached to the surveying pole. A distance between an attached reflector and/or GNSS receiver and the attached secondary sensor unit is also known and fixed. A method and computer program product for numerically correcting distance measurement errors due to reflector orientation and position with respect to a primary sensor, in particular a tachymeter.
