A Vehicle System for Autonomous Relative Survey of In-Water Ships

An new in-water ship hull relative inspection vehicle system has been developed in which navigation relative to inspection surface is done through a Doppler velocity logger and imaging is done through a DIDSON sonar. The system has working capability in zero visibility waters, with no external navigation system or compass. Several field tests demonstrate ability to perform full-coverage survey after locating and locking onto a wall.
