What is a DVL?

A Doppler Velocity Log (DVL) represents a sophisticated underwater navigation technology that precisely measures motion relative to the seafloor or water column. Think of it as an underwater speedometer that uses sound waves to track movement with remarkable accuracy. By bouncing acoustic signals off the bottom or particles in the water, DVLs provide crucial velocity data that enables underwater vehicles and vessels to navigate with confidence, much like how GPS guides vehicles on land.

The Evolution of DVL Technology

Teledyne RD Instruments has pioneered DVL technology, transforming it from a specialized tool into an industry standard for underwater navigation. Our continuous innovation has created systems that serve diverse needs across commercial, military, and scientific applications, establishing new benchmarks for precision and reliability.
