Abstract
An antenna system for satellite communication, mounted on a moving platform, includes an antenna assembly, a control and display unit, and an antenna steering unit. The antenna assembly includes mounted on an antenna mast. The antenna steering unit includes a support housing, a rotary joint comprising a BNC connector, an electronic magnetic compass. an angular velocity-sensing gyroscope, a global positioning system receiver, a signal processor and a motor. The direction of the antenna's azimuth axis is determined based on the heading of the moving platform determined by the signal processor. In one embodiment, the director elements, the antenna mast and the azimuth mast are all articulated on flexible joints comprising a cable and spring mechanism allowing the director elements to fold toward the antenna mast and allowing the antenna assembly to fold toward the azimuth mast for stowing.
