​DVL Navigation Solutions at Teledyne Marine


Our navigation product line provides a wide range of precision Doppler navigation solutions for acad​emic, commercial, and def​ense applications. Our Doppler velocity logs (DVLs) have quickly become the world-wide standard for commercial, military and academic applications alike. Explore our wide range of DVLs From Teledyne RD Instr​uments that continue to lead the way as the industry standard. ​



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.
