THREE AXIS ACTIVELY STABILIZED INMARSAT STANDARD-A ANTENNA

The SATCOM II antenna system, which features an active pedestal support that stabilizes a 1 meter reflector/feed combination, is described. Ship motion is measured below deck with an inertial measurement unit that is aligned with the ship axis and measures ship roll and pitch and angular velocities. By means of a microprocessor-based control board and software, these values are then translated in a coordinate transformation to the antenna angles required to compensate for the ship motion.
