Abstract
A satellite antenna includes first and second extensible booms and first and second sets of ribs carried by the respective first and second extensible booms. A Radio Frequency (RF) reflective film is carried by the first and second sets of ribs. First and second phased array antenna feeds are carried by the respective first and second extensible booms and directed toward the RF reflective film. First and second sets of fiducial devices are carried by the respective first and second sets of ribs. At least one camera is directed toward the first and second sets of fiducial devices to sense a physical distortion of the RF reflective film. A controller cooperates with the at least one camera to operate the first and second sets of phased array antenna feeds to account for sensed physical distortion of the RF reflective film.
