KATFISH
KATFISH is an actively stabilized Synthetic Aperture Sonar towfish that provides industry-leading resolutions of 2 x 2 cm SAS imagery with co-registered 3D bathymetry. With speeds of up to 10 knots, the system offers a significant advantage over slower-moving ROV and AUV-based systems, offering unparalleled Area Coverage Rates (ACR) and reducing survey times and operating costs.
KATFISH allows 3 x 3 cm resolution data to be viewed in real time on board the towing vessel, or sent remotely to a mothership or shore-based command station. It can be safely and rapidly deployed from a variety of vessels of opportunity with the use of an autonomous LARS (launch and recovery system) in either small USV or ISO20 form factors.
