Doppler Velocity Log (DVL) by Water Linked

World's smallest DVL 

Designed and developed to make high specification DVL performance available at an affordable price, while ensuring it’s simple for anyone to use. Enabled by proprietary transducer design, developing advanced algorithms and removing every millimetre of space that’s not absolutely needed.

DVL A50 - World's Smallest Doppler Velocity Log 
The Water Linked A50 is the world’s smallest Doppler Velocity Log (DVL). By utilising the latest technology Water Linked have been able to reduce the size and cost of the DVL, while delivering a level of performance previously not possible in a product so small.

Key features:

  • 5cm – 50m altitude range 300m or 600m depth rated

  • Ethernet and Serial interface

  • Imbedded computer for standalone operation

  • AHRS for increased accuracy

  • Extremely small size enabling easy mounting and integration

  • Web GUI with comprehensive diagnostic features

Thanks to the size and weight of the A50, the smallest ROVs and AUVs can now benefit from increased navigation and control.  Suitable for depths to 600m, the A50 allows small, inexpensive unmanned vehicles to perform tasks that would otherwise required a larger, more expensive vehicle.

Larger vehicles requiring high accuracy navigation also benefit from the size, weight, and cost benefits of this high accuracy DVL.

While typically integrated fully to the ROV or AUV for enhanced control, the integrated Attitude and Heading Reference System (AHRS) allows for dead reckoning positioning. This feature allows the A50 to generate an accurate track plot of the vehicles movements without the need to fully integrate with the vehicle control system.

DVL-A125 Miniature Long-Range DVL
The Water Linked A125 is the world’s smallest long range Doppler Velocity Log (DVL).  Utilizing the latest technology, Water Linked has reduced the size and cost of the DVL, while delivering a level of performance previously not possible in a product so small.

Key features:

  • 5 cm – 125 m altitude range

  • 600 m or 3000 m depth rated

  • Ethernet and Serial interface

  • Imbedded computer for standalone operation

  • AHRS for increased accuracy

  • Extremely small size enabling easy mounting and integration

  • Web GUI with comprehensive diagnostic features

Groundbreaking performance-to-size ratio
Capable of maintaining bottom lock at speeds of up to 9 meters per second, and with a maximum altitude of 125m, the A125 is the perfect DVL for ROVs, USVs and AUVs. The ability to also operate at an altitude as low as 5cm means the DVL will work at extremely short range as well as long range.

While the size and weight of the A125 allows this DVL to be used on the smallest of vehicles, having a depth rating of 3000m means this high performance DVL can also be used on vehicles that operate at these extreme depths.

Although a DVL is typically integrated fully to the vehicle for enhanced control, the integrated Attitude and Heading Reference System (AHRS) within the A125 allows the DVL to be used for dead reckoning positioning. This feature allows the A125 to generate an accurate track plot of the vehicles movements without the need to fully integrate with the vehicle control system.
