DVL-A50-Water-Linked-2

DVL | WaterLinked A50

Water Linked A50 DVL provides estimated velocity relative to the seafloor using acoustic waves from four transducers. In combination with Deep Trekker BRIDGE sensor technology, greatly improve the ability to determine speed, heading as well as automated station holding.

Doppler velocity log ROV attachment for stabilization and autonomy

Mounted on the bottom of the REVOLUTION ROV, the Water Linked A50 DVL not only calculates the ROV's altitude (depth from the bottom) but also receives real-time data on estimated speed. When integrated with Deep Trekker BRIDGE sensor technology, the DVL enhances positioning accuracy and station holding, even in challenging currents.

DVL for search and recovery missions

In search and recovery missions, the DVL plays a crucial role in maintaining an optimal altitude for the imaging sonar. For instance, it ensures the sonar remains at a precise depth, such as 15 meters, with the sonar oriented at a 15-degree angle downward. This configuration enhances the effectiveness of the sonar in capturing detailed images during underwater search operations.

Position/Station holding with DVL

The DVL is instrumental in maintaining precise positions during various operations. Whether conducting inspections against a current, deploying a manipulator, or using a laser scanner, the DVL aids in achieving steady and controlled ROV positioning. This capability ensures optimal conditions for detailed inspections and intricate tasks, enhancing overall operational efficiency and accuracy.

Automatic altitude hold

Employing a DVL on the ROV facilitates automatic altitude hold, ensuring course stability in currents and maintaining a consistent altitude above the seafloor. This feature is particularly crucial for benthic surveys, as it prevents collisions with the seafloor and minimizes sediment disturbance. The result is a clearer and more effective benthic survey, optimizing data collection and survey outcomes.
