AUV ECA A-9S

A9S / AUV / Autonomous underwater vehicle

A9-S is the portable configuration of the A9 autonomous underwater vehicle, AUV, of the ECA group, dedicated to seabed images. The vehicle's stability and navigation precision provide the best operating conditions for obtaining the highest quality side-scan sonar images. In addition, the AUV's built-in sonar is one of the best solutions available on the market. Triton SSS software can be used to create the highest quality side scan mosaics.
