New SEABER AUV Brings High-End Survey Capability at Lower Cost

Edited By: Ed Freeman

French AUV manufacturer SEABER announces the launch of RAVEN®, a new generation of compact AUVs for mine countermeasures (MCM) and survey. High-precision navigation, side-scan sonar, HD imaging, magnetic detection: RAVEN® targets the performance of high-end conventional autonomous underwater vehicles (AUVs) at one-third of the price.

Weighing 13 kg with a 12 cm diameter, RAVEN® can be deployed by a single operator, while carrying technologies until now reserved for larger and more expensive platforms.

Precision Navigation Powered by LYNX®

At the heart of RAVEN® is LYNX®, SEABER’s proprietary optical-based inertial navigation system. Its drift remains below 0.2% of distance traveled on straight-line trajectories, with even better performance on lawnmower survey patterns. A dual-antenna GNSS receiver ensures more accurate initialization and features anti-jamming capabilities, essential in contested or GNSS-denied environments.

Combined with a DVL, this accuracy opens up new possibilities for seabed mapping, underwater inspection, scientific research, and defense missions.

Two Configurations for Detection and Inspection

RAVEN® carries a side-scan sonar (600/1200 kHz or 900/1800 kHz) and comes in two versions:

RAVEN SCAN-MAG integrates a magnetometer capable of detecting and locating submerged metallic objects, including naval mines and shipwrecks.
RAVEN SCAN-LUMEN combines a high-definition camera with a 24,000-lumen lighting system for visual inspection, even in demanding underwater environments.

High-End Performance at One-Third of the Price

RAVEN’s breakthrough is also economic. SEABER aims to deliver performance comparable to high-end conventional AUVs at one-third of their price. This positioning could make advanced underwater technology accessible to a much broader range of users and enable large-scale AUV deployment.

Having helped democratize micro-AUV technology with its YUCO range, SEABER now brings the same approach to the compact AUV segment.
