TRIAXIAL ROTARY SUPPORT Russian patent published in 2014 - IPC H01Q3/08 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to antenna engineering. The triaxial rotary support comprises an azimuthal rotary mechanism consisting of a column in form of a steel pipe on which is mounted an azimuthal drive, around which an azimuthal truss rotates on bearings, and an elevation rotary mechanism consisting of an elevation drive and an elevation rotary platform consisting of an elevation axle in form of a steel pipe and a first steel plate welded thereto, to which a beam with two mirror rotation supports is mated, and a second steel plate welded on the opposite side to the elevation axle, to which is attached a counterweight and a mounting bracket for a screw-jack, a mounting bracket for a screw-jack lug attached to a mirror, a screw-jack with a drive, wherein the azimuthal and elevation rotary mechanisms and an inclination angle mechanism are provided with angular position sensors.

EFFECT: eliminating blind areas in the region of elevation angles adjacent to the zenith, for the azimuthal-elevation mode and in the region of elevation angles adjacent to the horizontal, for the elevation-elevation mode while maintaining the possibility of balancing the weight of the mirror antenna using counterweights.
