MARVEL micro-AUV offers a new, affordable  approach in single-task AUVs 

A range of micro-AUVs carefully designed toward these key attributes:

  • High reliability

  • Precise navigation w/acoustic positioning and wireless communication

  • Ease of deployment/retrieval

Common Specs
  • Depth rating: 300m

  • Weight: 9.5kg to 10.5kg

  • Length: 98 to 128cm

  • Diameter: 12cm

  • Speed: 2.5 - 6 knots

  • Endurance: Up to 8 hours

  • Rechargeable batteries



  • A uniquely reliable AUV that combines exceptional performance and low maintenance
  • Operable in all types of coastal waters
  • Delivered as a single task “off-the-self” micro-AUV
  • Affordable and deployed easily and swiftly by one person
A robust bio-inspired design

MARVEL is compartmented in 2 sections. The center/rear section is factory sealed and not user accessible. This dry compartment contains the navigation system, including batteries, actuators, localization sensors and embedded electronics. The wet section located in the front (nose) contains the sensor payload, and is user-accessible. The wet payload section is also equipped with necessary connectors for quick plug-and-play integration of new sensors.

Integrated SeaTrac USBL positioning and acoustic modem by Blueprint Subsea

The SeaTrac positioning system combined with a topside dual-antenna GNSS-RTK provides for improved navigational accuracy. 
While underwater the acoustic modem provides real-time status updates and the ability to wirelessly send commands to MARVEL.

SeaTrac USBL Specifications

  • Acoustic range: 1km radius horizontal, 1km vertical

  • Range Resolution: +/-0.1m

  • Velocity of Sound Range: 1300ms-1 to 1700ms-1

  • Beacon Velocity: Active Doppler compensation, up to 15kts

High-performance navigation with INX

INX is SEABER’s highly accurate proprietary navigation system for micro-AUVs.  Based on SEABER’s advanced underwater navigation algorithms, INX provides high-performance navigation and a highly configurable platform to optimize and continuously improve the navigation experience.  DVL and depth sensors are fully integrated, providing a reliable navigation system in an autonomous platform.

Intuitive mission planning with SEAPLAN

SEAPLAN is a powerful and modern GUI that offers programming flexibility, intuitiveness and ease of use.  A wide range of navigational patterns can be programmed, and payload sensors can be easily programmed to activate at various intervals. SEAPLAN offers unique navigation modes dedicated to specific payloads, such as « shutdown surfacing », ideal for CTD and PAM.  Read more on SEAPLAN

Key features to ensure a smooth recovery

MARVEL is highly visible at the surface under all light conditions, thanks to its bright orange body color and powerful flashing LEDs. To ensure surface communication, MARVEL’s mast is equipped with 3 types of wireless communication antennas: satellite, GSM and radio.  Furthermore, a handheld remote-control (RELOC) displays MARVEL’s GPS position upon surfacing and includes provides a handy “return to home” function.

SEAPLAN Software

User-friendly mission planning tools and AUV dashboard Program your mission, deploy and forget it!

In a single view, see and edit the elements of the mission (path, speed, payload, deployment and recovery points). Even untrained users can easily prepare a mission, thanks to its modern graphical interface and high-level navigation patterns. Advanced users can access low-level navigation functions, payload activation and parameters with the same ease-of-use. Multiple online maps are available in SEAPLAN, or create custom offline maps by importing most  any standard format map data.

SEAPLAN is also the AUV dashboard. At a glance you have access to MARVEL status, sensor state and mission feasibility. Smart mission analysis audits autonomy, speed and accuracy considering MARVEL’s capabilities and field parameters. Moreover, a robust protocol and log analysis tools guarantee seamless security. It makes SEAPLAN a safe platform and gives users a great confidence in the success of every mission. MARVEL calibration, firmware updates and mission upload are all made simple and done wirelessly via SEAPLAN. Once the mission uploaded, the AUV will simply start when submerged.

Once the AUV is recovered, SEAPLAN connects to MARVEL and provides a clear mission debrief. Access the main mission indicators to quickly check whether any problems occurred and import the raw mission data in open formats.
