A DVL is a sonar system that measures motion under water. DVLs emit sound bursts along beams angled downward in various directions. Echoes that are scattered off the seabed are returned. Because the DVL sonar is aboard a moving vehicle,returning echoes carry a change in pitch; this is the Doppler Effect. Combining these readings tells how fast the vehicle is movingand in what direction.
The DVL1000 is the world’s smallest commercially available Doppler Velocity Log. It combines compact design with unprecedented functionality, being able to fly highe
The DVL500 is a universal Doppler Velocity Log that combines compact design with unprecedented functionality. It can fly higher in the water column and closer to the
