Abstract: An arrangement for one-man surveying, including a measuring station (1) and a target unit (2). A sighting-marker arrangement is provided which can be indicated by an indicator arrangement (7) on the measuring station. The measuring station (1) automatically takes a target seeking mode when the indicator arrangement (7) does not indicate the sighting-marker arrangement and a target following mode, when the indicator arrangement indicates the sighting-marker arrangement. The sighting-marker arrangement includes a combination of a first and a second sighting-marker unit. The first unit has a light source (8) on the target unit (2). The second unit has a light source (9) on the measuring station (1) and a reflector (11) on the target unit (2).
