Zusammenfassung:SATELLITE TRACKING ANTENNA SYSTEM A ship borne antenna using a gimballed mount for establishing a two degree of freedom unstabilized structure. A ring is mounted for rotation on a radome and carries an antenna mounted for rotation relative to the ring. The ring antenna are respectively driven by stepper motors. Variations in stability occurring by pitch, yaw or roll of the ship are corrected on a real time basis using a microprocessor that dynamically drives the ring and the antenna to maintain lock-on with a satellite.
