Abstract
Position determination method for a target point, using a geodetic measuring device, such as a total station or a theodolite, having a distance and angle measurement functionality, a sighting device, and a first radio module, and using a hand-held data processing device, such as a data logger for the measuring device, having a second radio module. The data processing device is positioned within a specified radius of the target point. As part of the method, a radio connection is established between the first and the second radio modules, and the position of the target point is determined. A rough distance between the first and the second radio modules is determined based on a propagation time of interrogation and/or response signals of the radio connection and is used to locate the target—as displaying, detecting, identifying, and/or sighting the target point—or to exclude further possible target point candidates.
