Application field

Information reception from civil aircrafts in-flight test

Information reception from missile in test or real conditions

Information recovery from drones for video transmission

Use frequency of few MHz up to Ka band

Turret mounted on mast head or distributed along the mast sections

Operating mode

The set of turret and control unit is equipped with tracking function. This fonction can be carried out by :

• Angular deviation : the turret re-positions the antenna dish according to the signal which has been received by the receiver
• Video : the turret is equipped with a camera and a video or thermal box which allow tracking the flying object by target setting

The turret can be equipped with 1 or several antennas according to frequencies which are involved

The turret can be fixed or portable
