Abstract:
1. A pedestal for a tracking antenna for obtaining rotational stabilization of the antenna about three axes, said pedestal comprising: a horizontal isolation assembly dimensioned and configured to isolate a support plate from horizontal vibration and shock of a base ring; a hub assembly including a support mounted on the horizontal isolation assembly rotatably supporting a rotating frame about a first azimuth axis; a vertical isolation assembly including an upright frame and a cross-level axis support slidably interconnected with a linear bearing assembly, the linear bearing assembly having a profiled rail slidably received within a complementary shaped bearing block, wherein the profiled rail can not twist axially relative to the bearing block; a cross-level frame pivotally mounted on the cross-level axis support about a second cross-level axis; and an elevation frame assembly supporting the tracking antenna and pivotally mounted on the cross-level frame about a third elevation axis.
