MARVEL-MBES, the most AUV used for seabed mapping

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-MBES AUV just makes AUV technology accessible. Using MARVEL-MBES is certainly one of the most simple and cost-effective ways to map the seabed. Equipped with a multibeam echo sounder from Imagenex MARVEL-MBES provides a great quality image with high stability, accurate navigation, and capable of managing coastal areas with waves and current.


The MARVEL-MBES 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-MBES is able to have a navigation accuracy equal to <5m absolute positioning within the USBL surface module range. SEAPLAN software provides an ideal and versatile interface for the MARVEL-MBES AUV and has pre-defined lawn-mover patterns to make a swift mission.
