1. Observation arrangement mounted on a vehicle, especially on a motor vehicle, which observation arrangement has a telescope mast extendable through an opening in the vehicle roof, on the upper end of which mast is mounted so as to pivot a platform supporting observation devices, characterized in that the telescope mast (3) is connected in the vicinity of its lower end (3b) to the vehicle (1) by means of a suspension (7, 8) allowing movement in two vertical planes lying perpendicular to one another and that a stabilizing arrangement, which orients the telescope mast (3) to the vertical irrespective of the position of the vehicle (1), is provided with two goniometers (5, 6), arranged in the vicinity of the upper end (3a) of the telescope mast (3) and measuring angular differences between the direction of the telescope mast (3) and the vertical direction occurring in two vertical planes lying perpendicular to one another and converting them into electrical signals, which goniometers (5, 6) are connected via a control unit (9) to two control elements (10, 11) effective in these vertical planes and acting on the lower end (3c) of the telescope mast (3). |
