Tasman DVL

Tasman DVL

13-May-2019

Next Generation DVL Technology 


Teledyne RD Instruments (TRDI) has announced the launch of its new next-generation Doppler Velocity Log (DVL), the Tasman DVL.  In 1995, Teledyne RDI designed and manufactured the industry’s first DVL, the Workhorse Navigator.  The Navigator remains the gold standard, with thousands of units delivered globally to provide precision, onboard navigation for subsea and surface vehicles.

The new 600/300 kHz Tasman DVL, with its reduced size, weight and increased range, has been designed to supersede this industry icon with increased accuracy, and an industry first innovative field replaceable phased array transducer design. With increased bottom tracking ranges from 0.15m to 420m, in up to 6,000m water depth, the Tasman represents the most advanced DVL technology available.

Stephen Apsey, Vice President of Engineering at Teledyne RDI explains, “We know the Workhorse Navigator has been a mainstay for many years.  We are certain the industry will be excited to see what 25 years of customer feedback and technology enhancements has produced. We have set the bar high for this next-generation DVL, and the performance we are seeing from the Tasman actually exceeds our initial design specifications.  We believe that the new features found in this unit, particularly the field swappable transducer, will be game a changer for vehicle manufacturers and rental companies around the globe.”


 
Patent pending technology allows you to bottom track up to 160 m altitude with the 600 kHz DVL, and 420 m with the 300 kHz DVL while delivering the same low power consumption and high accuracy.
