kr 75 900,00

The DVL-A50 is – by far – the world’s smallest commercially available Doppler Velocity Log.

The record breaking 5 cm min altitude makes the A50 extremely useful for working with tools close to the seabed.
With its unbeatable price/performance, the DVL-A50 is now establishing a new market standard.
Key Specifications:
Altitude 0.05 – 50meters
Frequency 1MHz
Long Term Accuracy ± 0.1cm/s

Finally a DVL suitable for small ROVs/AUVs!
The DVL is designed with small ROVs/AUVs in mind where it can be mounted without adding significant weight or drag to the vehicle.
While the A50 is the perfect fit for small vehicles looking for professional navigation features, the combination of low cost and high performance is also making it very attractive for much larger vehicles.
Advantages by using DVL on your vehicle
Accurate position hold for professional inspections and/or tooling interventions
Accurate micro movements like “move 1 inch to the right”
Travel over great distance and use “dead reckoning” to create the travelled path
Find home even while being out of reach of acoustic positioning systems like Underwater GPS
Accurate flight path which pairs very well with sonar imagery
Combine the DVL with our Underwater GPS system to get a high performance, professional navigation package!

>Long term accuracy: ±1.01 % (Standard version): ±0.1 % (Performance version)

Performance version has a long term velocity error margin of better than 1% which requires an export license if sold outside of Norway.
Water Linked will apply for the export license and ship the product when the license is received. This normally takes 1 week. Except for the price difference compared to the “Standard” version of the DVL, there are no additional costs involved.
