Waterlinked DVL A125

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.

Doppler Velocity Log (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.

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.

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.
