FIELD: physics.
SUBSTANCE: in a device for orientation of a unit (4) for transmitting at least one beam for angle of elevation of a target and/or azimuth, said unit is mounted on a fork (2) with possibility of rotation around the axis (XX) of the elevation angle of the target and is driven around this axis by a motor (13) mounted on the fork (2), which is mounted on a bearing surface with possibility of rotating around the axis (YY) of the azimuth perpendicular to the axis (XX) of the angle of elevation of the target, and is driven around this axis (YY) by a second motor mounted on the bearing surface, wherein at least one of the motors is a progressive wave piezoelectric vane-type motor.
EFFECT: high accuracy of orientation, reduced size, as well a power and material consumption.
