Abstract
Abstract A multi-axis antenna pedestal with two controlled axes configured with elevation over azimuth on a gravity and gyro stabilized platform. The assembly is suspended with right-angled pivotal axes in substantially the same horizontal plane, and structure pivoted about the upper two controlled axes is statically balanced and the center of gravity of the entire pivotally mounted assembly is on the vertical axis and below the gimbal plane. The platform structure includes at least one gyro motor and rotor system pivotally mounted in the platform structure on an axis parallel to one of the right angled pivotal axes of the platform pivotal mounting. The center of gravity of the one gyro motor and rotor system is below its pivotal mounting in the platform structure, and when two such gyro motor and rotor systems are employed the pivotal mounting axes of each parallels an individual axis of the platform pivotal mounting.
