A125 Doppler Velocimeter
The world's smallest remote DVL, ideal for ROV/USV/AUV!
DVL A125 is by far the smallest long-range Doppler velocimeter in the world.
DVL A125 is building a new market standard with its high-performance, ultra-small 4-beam configuration, open API interface protocols, and low-cost.

Seamless integration with BlueROV
Software algorithms are constantly being updated
Simple and easy-to-use GUI user interface
You can use a standard web browser to update the orientation and path in real time
Rich functions and easy to use
It can display the height and speed direction of DVL from the bottom in real time
ROV positioning mode can be realized
Opening the positioning mode greatly improves the anti current ability of ROV
High precision underwater positioning can be achieved
The long-term positioning accuracy of the standard version can reach ± 1.01%, while that of the performance version can even reach ± 0.1%
