ABSTRACT:
The invention concerns a device for checking radio aerial navigational aids.
In the device according to the invention, the infra-red scanning head is mounted on a turret by means of two groups each comprising a tachometric generator-motor unit and an angular coder and respectively mounted along the inclination axis and the bearing axis. The motors are supplied by voltages characteristic of the angular aiming errors furnished, after processing, by the scanning head. The orientable beacon on board the aircraft is controlled by orientation servomotors supplied by a recopying system.
