Arrangement for performing position determination
First Claim
1. An arrangement for performing position-determining and/or setting-out work for one-man surveying, which locks a measuring station on a target unit comprising:
- (a) a measuring station (1) provided with an instrument which can be rotated about a horizontal axis with the aid of a steerable vertical-angle motor (3) and about a vertical axis with the aid of a steerable horizontal-angle motor (4);
(b) a steering and computing unit (12) in said instrument having memory and being connected to said motors (3,
4);
(c) a target unit (2); and
a seeking and locating arrangement for positioning said measuring arrangement with respect to said target unit comprising;
(d) a first sighting-marker unit comprising a light source (8) placed on said target unit (2) and arranged to be directed towards said measuring station (1) and having a first light characteristic;
(e) an indicator arrangement (7) which is adapted to detect transmitted light from said first sighting-marker unit on said measuring station for detecting said first sighting-marker unit when said instrument is in alignment with said target unit; and
(f) a second sighting-marker unit (8, 9,
11) comprising a light source (9) placed on said measuring station (1) and having a second light characteristic, a reflector (11) placed on said target unit (2), the light beam reflected by said reflector (11) being detectable by said indicator arrangement (7) on said measuring station;
(g) said steering and computing unit steering said motors to turn said measuring station to be directed to said target unit (2) when said indicator arrangement (7) does not detect said first and second sighting-marker units in accordance with predetermined rules, and switching into a target tracking mode with servo control directed towards said target unit when said indicator arrangement indicates said sighting-marker first and second units.

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).
