ABSTRACT:
An antenna assembly for operation on a moving platform includes a base to be mounted on the moving platform, an azimuthal positioner extending upwardly from the base, and a canted cross-level positioner extending from the azimuthal positioner at a cross-level cant angle canted from perpendicular. The canted cross-level positioner may be rotatable about a cross-level axis to define a roll angle resulting in coupling between the azimuthal and canted cross-level positioners. The antenna assembly may also include an elevational positioner connected to the canted cross-level positioner resulting in coupling between the elevational and the azimuthal positioners because of the roll angle. An antenna may be connected to the elevational positioner. A controller operates the azimuthal, canted cross-level, and elevational positioners to aim the antenna along a desired line-of-sight and while decoupling at least one of the azimuthal and canted cross-level positioners, and the azimuthal and elevational positioners.
