Abstract
A gravity stabilized drive mechanism varies the orientation of an underwater ultrasonic transducer in both azimuth and elevation while stabilizing the transducer against the pitching and rolling of a ship. The transducer is freely suspended by a universal joint from a vertical tilt control shaft. The tilt control shaft passes through a hollow azimuth control shaft which, in turn, is rotatably mounted on a platform attached to the ship. Elevation of the transducer is adjusted by rotating the tilt control shaft, and azimuth of the transducer is adjusted by rotating the azimuth control shaft.
