designed and fabricated a remote positioning system for an underwater
acoustic source array in support of the Navy's Critical Sea
Test Program. Due to the directionality of the array, precise
positioning was required to ensure repeatability and an accurate
acoustic measurement. Specific tasks included:
and fabricated a 360 degree rotator to supply 250 foot pounds
of torque to handle the high inertial loads and to hold the
acoustic array in the stop position in depths to 2000 feet.
and fabricated control and display unit which provided control
of the rotator DC stepper motors and provided display of array
orientation in azimuth and D/E angles.
