A18-S / AUV / Autonomous underwater vehicle
A18-S is the 3D image sonar configuration of the A18 autonomous underwater vehicle of the ECA Group. This AUV is designed to develop precision 3D inspections of the seabed. It is deployed from a surface vessel and an LARS allowing automatic recovery can be used. The vehicle operates autonomously at depths of 300 meters with 21 hours of battery life and is easy to transport by plane.
Characteristics:
- AUV with synthetic aperture interferometric sonar (ISAS)
- Easy to deploy and recover in bad sea conditions
- Extended autonomy and coverage capabilities
- Very easy to use mission management system
Applications for the defense and security sector:
- Protection of critical infrastructure: monitoring of vessels for protection at sea
- Rescue and rescue operations
