Abstract

A geodetic measuring system having at least one reference component which defines a reference point, wherein an absolute position of the reference point is known, and at least one new-point determination component which derives a relative new-point position. It is also possible to derive mutual relative reference information between the reference component and the new-point determination component, in particular for the purpose of referencing with respect to the reference-point position. The measuring system also has an automotive, unmanned, controllable air vehicle, wherein the air vehicle has the reference component which provides the at least one reference point as a mobile reference point. The air vehicle is also designed in such a manner that the reference component can be spatially freely displaced by the air vehicle, in particular can be positioned in a substantially fixed position.

a mutual relative reference information between the reference component and the new point determination component is derivable for the purpose of referencing with respect to the reference point position;
the surveying system has an automotive, unmanned, controllable air vehicle;
the air vehicle carries the reference component, by which the at least one reference point is provided as a mobile reference point; and
the air vehicle is implemented in such a manner that the reference component is freely displaceable spatially and is positionable substantially fixed in position by the air vehicle relative to the new point determination component.

2. The geodetic surveying system as claimed in claim 1 , wherein
the surveying system has a reference point determination component for the determination of the absolute reference point position in an absolute coordinate system, so that a line of sight between the reference component and respectively the new point determination component and the reference point determination component can be indirectly generated by a specific positioning of the reference component, and a referencing of the new point position in the absolute coordinate system can be carried out, and/or
a number of reference points can be generated by the spatial displacement of the air vehicle, and
the air vehicle is displaceable and positionable in an altitude range of 1 m to 1000 m, and/or
the surveying system has an analysis unit for
detecting and assigning;
the absolute reference point position, which is determined and provided by the reference point determination component, of the reference point; and
the relative reference information between the reference component and the new point determination component including measured angles and/or a distance to the respective reference point, wherein the relative reference information can be determined and provided by the new point determination component as a function of the reference point position and a position of the new point determination component; and
