MARVEL-3DSS, the most compact UUV for high resolution swath bathymetry

MARVEL-3DSS micro-AUV just make AUV technology accessible. Using MARVEL-3DSS is certainly nowadays one of the most simple and cost-effective way for high resolution swath bathymetry.

Equipped with a 3D Side Scan Sonar from Ping DSP MARVEL-3DSS provide with a great quality of image with high-stability, accurate navigation and capable of managing coastal areas with waves and current.

MARVEL-3DSS is equipped with underwater acoustic positioning and communication module.

With an autonomy up to 8 hours, and speed up to 6knots, and depth rated at 300m.

Thanks to the INX navigation, DVL and acoustic positioning, MARVEL-3DSS is able to have a navigation accuracy equal to <5m absolute positioning within USBL surface module range.

SEAPLAN software provides an ideal and versatile interface for the MARVEL-3DSS micro-AUV and have pre-defined lawn-mover patterns to make a swift scan mission.

Thanks to its mission programming savings and updates, SEAPLAN facilitates discovery of new area as well as repetitive mission in similar locations.

MARVEL-3DSS is provided with all the necessary functions to be ready-to-deploy :

• INX Navigation system
• DVL
• SEAPLAN Software
• Embedded rechargeable batteries
• SEACOMM
• Field case and accessories
• Acoustic positioning and communication module
• Autonomous buoy with USBL unit and dual antenna GNSS-RTK module
