Geodesic measurement system and method for identifying a target unit having a geodesic measurement device

A geodesic measurement system comprising:

• a geodesic measurement device;
• and
• a plurality of target objects, which form a target object set, wherein each of the target objects is respectively assigned a unique identification code such that the target objects can be differentiated from one another on the basis of the identification code, wherein:
• the measurement device has a distance and angle measuring functionality for determining the position of the target objects and at least one radiation source for emitting an optical beam in a defined spatial direction;
• one of the target objects is embodied as a target unit and has a reflector and a detector for receiving the beam;
• the measurement device is designed for emitting the beam in such a way that the identification code of a sought target object from the target object set can be modulated as a code to be sought on the beam;
• the target object has an evaluation component connected to the detector and serving for checking a correspondence between the code modulated on the beam and the dedicated identification code of the target unit and a transmitting component for the communication—effected upon correspondence—of a reactive confirmation signal to the geodesic measurement device;
• and
• the measurement device has a processing component, which is designed for identifying the target unit from the target object set on the basis of the reactive confirmation signal.
