Position determination method and geodetic measuring system

A geodetic measuring system, comprising:

• a geodetic measuring device, including:
• a first radio module;
• a distance and angle measurement function configured to determine spatial positions of reflecting objects that represent target point candidates of a candidate set;
• and
• a sighting device;
• and
• a handheld data processing device spatially linkable to the target point including a second radio module configured to communicate with the first radio module;
• wherein:
• the geodetic measuring device or the handheld data processing device is configured to determine a radio approximate distance from the first to the second radio module with the aid of a propagation time of interrogation and/or response signals of a radio link between the first and the second radio modules;
• the geodetic measuring device or the handheld data processing device is configured to determine target point candidate distances between the sighting device and the target point candidates of the candidate set, wherein the target point candidate distances are determined based on reflected optical signals from the target point candidates;
• the geodetic measuring device or the handheld data processing device is configured to localize the target point by identifying the target point from the candidate set based on the radio approximate distance so that a user can easier identify the target point;
• the geodetic measuring system further comprises a focus control for the sighting device for automatic focusing as a function of the radio approximate distance;
• and
• the geodetic measuring system further comprises a unit for identifying the target point from the candidate set based on the radio approximate distance, wherein the unit for identifying is designed as an arithmetic logic unit for identifying the target point from the candidate set by filtering the target point candidate distances as a function of the radio approximate distance.
