AUV A18D

A18D / AUV / Autonomous underwater vehicle

A18-D is the mid-size autonomous underwater vehicle of the ECA, AUV group for deep water applications. It is dedicated to the precise exploration of the seabed in 3D. It performs autonomous missions from a depth of 21 hours up to a depth of 3000 m and is easy to transport by plane for missions abroad. This system can be delivered with an LARS which enables automatic underwater recovery and Triton Imaging software applications for further data processing.

Characteristics:

- Lightweight vehicle for deep water

- Ease of deployment and recovery in poor sea state conditions

- Easy deployment for missions abroad (ISO container transport)

- Extensive coverage and resistance capabilities

- User-friendly mission management system

- Flexibility of the load of the sensor.

Applications for the defense and security sector:

- Naval search and rescue operations

Applications for the maritime sector:
