Summary Specs Gallery

HAUV is a two-man-portable hovering AUV designed for ship hull inspection. Equipped with a high-resolution imaging sonar, it surveys ship hulls and other structures with minimal prior knowledge. While surveys are executed autonomously, the operator can manually control the vehicle to further observe features of interest identified in the real-time data.

CONTACT RELOCATION – HAUV can autonomously locate and relocate contacts on a ship’s hull with a precision of better than 2 meters CEP 50.

EASE OF OPERATION – The system can be unpacked, checked out and launched from a small boat or pier in less than 30 minutes, and the field-swappable battery and removable data storage module enable rapid turnaround between missions. An intuitive mission planning tool enables dives to be planned in a matter of seconds, and data retrieval and reporting occur automatically.

HIGH-QUALITY DATA – The integrated DIDSON™ sonar provides high-resolution sonar images that can be viewed in real time over the vehicle’s fiber optic tether. Data can also be post-processed into near-photo-quality images or mosaics using third-party software.

PRECISE MANEUVERABILITY – HAUV uses thrusters to hover, rotate in place and translate in any direction, enabling operations in confined areas. A fiber optic tether allows remote manual control of the vehicle for added maneuverability.
