Blueye X3 Equipment

DVL A50

The DVL A50 is the smallest DVL on the market with outstanding performance. This sensor provides velocity measurements relative to the seabed with a range of up to 50 meters altitude. With the Blueye Smart Connectors, there is no configuration required to integrate this sensor. We have done all the demanding work for you.

Station Keeping and Dead Reckoning position

With velocity measurements, it is possible to lock the position of the vehicle with a new control mode called station keeping. This mode simplifies inspections and monitoring even further by keeping the ROV locked in one position using the sea bottom as a reference. Simply push a couple of buttons on the controller and the ROV keeps the chosen position without constant input on the controller.

Since we integrate all external equipment with our Blueye Smart Connectors, the Blueye App will instantly recognize the DVL input and start the necessary programs for you to get started. There is no need for you to do any configuration yourself.

The A50 also provides a dead reckoning position that can be used for navigation on a map.

Use cases for DVL:

  • Mapping of more extensive areas.

  • Inspections of larger or longer structures to hold a fixed position from the object.

  • Situations where you really need to concentrate on what you see on the screen.

  • Strong current and challenging environment.

  • In general, helping the ROV pilot understand where the vehicle is located at all times.
