Abstract

An antenna steering system is provided that includes a plurality of gyro sensors fixedly located in close proximity to an antenna, for example a phased array antenna. The gyro sensors measure angular rotation of the antenna about an X-axis of the antenna, about a Y-axis of the antenna and about a Z-axis of the antenna. The gyro sensors communicate the angular rotation measurement data to a beam steering phase controller (BSPhC). The BSPhC utilizes the angular rotation measurements to determine a predicted amount of movement, i.e. a change in geolocation and/or orientation, of the antenna within a specified time period. Based on the predicted amount of antenna movement, the BSPhC adjusts a beam pointing angle of the antenna, i.e. steers the antenna, to compensate for the predicted amount of movement.
