Abstract
An arrangement for the vertical orientation of a geodetic instrument over a ground point, comprises an optical observation device for visual sighting of the ground point with a target beam, a laser device for generating a laser beam, and an optical in-coupling element by which the laser beam and the target beam can be coupled into a target axis impinging vertically on the target point. In this way, an exact orientation of the geodetic instrument can be achieved under all light conditions. The geodetic instrument retains its compact dimensions. In addition, a laser in a lower hazard class can be used.
