Abstract

An antenna mounting structure is supported and oriented by three linear hydraulic actuators responsive to linear position transducers of a passive stabilization system serving as a vertical reference for keeping an antenna precisely pointed at a geostatically satellite during motion disturbances. The antenna is assembled with each of the linear actuators connected thereto through a gimbaled mount which facilitates accommodation of the requisite angulation thereof necessitated by motion in adjacent actuators. Response in each actuator is derived through an independent linear servo loop directly communicating with a linear position transducer constructed in scaled replication of the respective antenna actuator geometrical configuration and assembled to an inertially stabilized platform. A proportional error signal is thereby generated in the linear position sensors which effectively comprises a mechanical analog computer adapted for integrating pitch, yaw, roll motions and directly converting them into the requisite triaxial linear command signals for the linear actuators. The triaxial control facilitates compensation of pitch, yaw, roll motions while maintaining a preselected polarization configuration.
