A9-E is the configuration of ECA Group A9 man portable Autonomous Underwater Vehicle, AUV, for environmental monitoring. In addition to the seabed image acquisition, it will record bathymetric data as well as environmental information such as water turbidity, conductivity, temperature, fluorescence, dissolved oxygen or pH. Mission planning and monitoring are done through a user friendly software which allows you to follow the vehicle at any time during its mission.
