Geodesic marking system for marking target points

The system (1) has geodetic position determination arrangement (20) to determine external actual position of automotive, unmanned, remotely controllable air vehicle (10) such as aircraft. A control unit is configured such that vehicle is positioned continuously in defined target position (6) relative to position of target point (5). The control unit is configured to control marking unit (15) for marking target point based on actual position, desired position and defined marking direction (14), so that target point marking is performed with geodetic accuracy in marking direction. Independent claims are included for the following: (1) method for controlling marking of known target point; (2) automotive, unmanned, remote-controlled target device; (3) marking arrangement of known target point; and (4) computer program product for controlling marking of known target point.
