MARVEL-MAGNETO, the most compact AUV detecting magnetic anomalies

Seaber’s MARVEL is the new generation of AUV meant for defense applications deployed and recovered with confidence. The MARVEL range is used more for defense-oriented sectors such as security, Coast Guard, MCM missions, and ASW training.


The MARVEL-MAGNETO AUV just makes AUV technology accessible. Using MARVEL-MAGNETO is certainly one of the most simple and cost-effective ways to detect magnetic anomalies. Equipped with a fluxgate magnetometer sensor from Sensys MARVEL-MAGNETO provides a great quality image with high stability, accurate navigation, and is capable of managing coastal areas with waves and current.

MARVEL-MAGNETO is equipped with an underwater acoustic positioning and communication module. With an autonomy of up to 8 hours, and speed of up to 6knots, and a depth rated at 300m. The INX navigation, DVL, and acoustic positioning, MARVEL-MAGNETO is able to have a navigation accuracy equal to <5m absolute positioning within the USBL surface module range. The SEAPLAN software provides an ideal and versatile interface for the MARVEL-MAGNETO AUV and has pre-defined lawn-mover patterns to make a swift scan mission.
