Abstract : The patent describes an apparatus for determining the position in azimuth of a surface vessel with respect to an underwater sonar signal source, irrespective of the motion of the surface vessel. It comprises a hydrophone which is capable of determining the azimuth of an underwater sonar signal source with respect to the roll and pitch axes of the surface vessel, and a universal joint, which connects the hydrophone to the surface vessel, its two axes of rotation being parallel to the roll and pitch axes of the surface vessel, thereby effectively permitting the hydrophone to rotate about the roll and pitch axes of the surface vessel.
