Abstract
A surveying system for surveying and tracking a movable target object that defines a target point includes a surveying device with a sighting unit defining a target axis and a detector for generating a continuously current amount-of-deviation signal dependent on a deviation from an optimal target orientation. A second unit on the target object side enables continuous determination of movements and/or positions of the target object with reference to an external coordinate system. The surveying system includes a target point tracking mode in which respective first measurement data currently generated by the first unit and the respective current amount-of-deviation signal and respective second measurement data currently generated by the second unit are continuously aggregated. On the basis thereof, a control signal is derived for continuous automatic motorized modification of the target axis orientation such that the target axis continuously aims at the target point.

16. A surveying system for surveying and tracking a movable target object that defines a target point, comprising:
-
a surveying device that constitutes a first unit, with position determining functionality for determining the position of the target point with reference to an internal coordinate system, wherein the surveying device includes; a base; a targeting device defining a target axis, wherein the alignment of the target axis is variable relative to the base in a motorized manner for precise sighting and tracking of the target point; a photosensitive areal detector for continuously generating a respectively current offset signal directly dependent on a direction and an extent of a deviation between a respectively current, actual alignment of the target axis and a fictitious alignment of the target axis that is aimed highly precisely at the target point; angle measuring functionality for continuously precisely detecting the current alignment of the target axis; and distance measuring functionality for continuously determining the respectively current distance to the target point; a second unit, provided on the target object side, for providing a functionality for continuously determining movements and/or positions of the target object with reference to an external coordinate system, said functionality being independent of the position determining functionality of the first unit; and a supervisory unit connected to the first and second units in terms of data and having evaluation, data processing and control functionality, wherein; the surveying system has a target point tracking mode, in the context of which, in a manner automatically controlled by the supervisory unit in accordance with a predefined algorithm; first measurement data respectively currently generated on the part of the first unit, said first measurement data being at least dependent on the respectively current alignment of the target axis and the respectively current offset signal, and second measurement data respectively currently generated on the part of the second unit, said second measurement data being dependent on the respectively currently detected movements and/or positions of the target object, are continuously aggregated and, on the basis thereof, a control signal is derived for continuously automatically changing the alignment of the target axis in a motorized manner in such a way that the target point is continuously sighted by means of the target axis. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
