ABSTRACT:
A method for determining the position of a reflector rod provided with a reflector, using a sighting beam emitted from a base station is disclosed. The reflector and a first position sensor define a first coordinate system. The direction of the sighting beam to the reflector is measured from the base station in a second coordinate system, using horizontal and vertical angles. A second position sensor arranged in the direction of the sighting axis of the base station determines the location and orientation of the reflector rod. Measurement data in the first coordinate system is generated to determine the spatial orientation of the reflector relative to the light beam. Imaging optics are used to image the reflector on the second position sensor. The position of the reflector in the second coordinate system and the distance from the base station to the reflector are determined.
