A stabilization system is provided with at least one sensor to measure and correct orientation of a platform relative to an inertial reference frame. A roll motor is affixed to a platform for pivoting the platform about a roll axis and an elevation motor is configured to rotate the platform about an elevation axis. A rotation motor pivots the platform about an azimuth axis. A control system using the sensor measurements, actuates the roll motor, elevation motor and the rotation motor to maintain a substantially constant orientation of the platform relative to the inertial frame of reference. The rotation motor, the elevation motor and the roll motor are spaced apart from each other along the azimuth axis.

Three axis stabilization platform

An antenna radome assembly has a radome base and an annular stationary bearing plate attached to and spaced from the radome base. A rotary joint has a fixed portion attached to the stationary bearing plate and a rotating portion extending through a central opening of the stationary bearing plate. A rotating platform is attached to the rotating portion of the rotary joint. The rotating platform includes a circular recess extending into the rotating platform from a first side. The stationary bearing plate is disposed completely within the circular recess. An annular bearing assembly is disposed within the circular recess between the rotating platform and the stationary bearing plate. The bearing assembly is in contact with the rotating platform and the stationary bearing plate, and the rotating platform rotates with respect to the stationary bearing plate and the radome base.
