Abstract
A target equipped with a reflector can be tracked in a measuring system including a laser tracker. The reflector is tracked by means of a tracking unit in a normal tracking mode and by means of a surveying device in an extraordinary tracking mode. A capturing unit having a detection range lying between the detection ranges of the tracking unit and of the surveying device is also present. If the target cannot be detected by the tracking unit but can be detected by the capturing unit, the orientation of the tracking unit is controlled according to a measurement by the capturing unit. If the target can then be detected by the tracking unit, a transition to the normal tracking mode is initiated. If the target can be detected only by the surveying device, the orientation of the tracking unit is controlled according to a measurement of the surveying device.
