Patent ID: 6859185

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