DVL A50 – The world’s smallest DVL

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.

When size matters


Thanks to the size and weight of the A50, the smallest ROVs and AUVs can now benefit from increased navigation and control. This allows these small vehicles operating in water depths down to 600m to perform tasks that would have previously required a larger and more expensive vehicle.

Although a clear benefit for small vehicles, larger vehicles requiring high accuracy navigation features also benefit from the size, weight, and cost benefits of fitting this high accuracy DVL.

While typically integrated fully to the ROV or AUV for enhanced control, the integrated Attitude and Heading Reference System (AHRS) within the A50 allows the DVL to be used 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.
