Underwater Acoustic Array Positioner

C&M 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:

  • Designed 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.
  • Designed 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.
  • Provided interface diagrams for system installation.
  • Prepared operation and maintenance manual for the system.
