The Remote Minehunting System (RMS) AN/WLD-1(V)1 vehicle (RMV) currently does not have a forward-looking sonar (FLS), or any other underwater obstacle avoidance sensor. This means that the RMV itself, while towing a sonar array, will be "flying blind" in littoral environments that are expected to… More

An acoustic device capable of acoustically transmitting wide-bandwidth information through the pressure hull of a submarine requires careful design but appears feasible based on prior work performed at Sonatech. The current application addresses only out-board to in-board, or wet-side to dry-side,… More

Sonatech proposes to develop the operational concept for an underwater "GPS-type" acoustic positioning system (UAPS) deployable from surface craft or helicopter, providing multiple users the ability to navigate with GPS precision underwater. UAPS has application for unmanned underwater vehicles… More

Sonatech proposes to continue the development of the operational concept for an underwater "GPS-type" acoustic positioning system (UWAPS), to be deployable from surface craft or hovering helicopter, and to provide multiple users the ability to navigate with GPS precision underwater. UWAPS has… More

Naval Special Warfare (NSW) teams often use underwater vehicles (UVs) for clandestine transport into highly sensitive littoral areas. The current sonar suites on the existing vehicles do not include a system for detecting and identifying active sonar transmissions, making the vehicle and the SEALs… More
