Teledyne RDI’s Tasman DVL: Redefining the Gold Standard in Subsea Navigation
Designed for Versatility to Serve a Range of Subsea and Surface Vessels
Teledyne RDI’s Tasman Doppler Velocity Log (DVL) marks a significant leap forward in subsea navigation technology, building on decades of innovation to deliver high-performance positioning and guidance for a wide spectrum of marine vehicles. As the latest generation in DVL technology, the Tasman is engineered to meet demanding operational requirements while remaining economically viable, making it the new gold standard for underwater navigation.
With bottom-tracking ranges from just 0.15 m up to 500 m and operational depths reaching 6,000 m, the Tasman serves a diverse fleet, from compact ROVs and large-diameter AUVs (such as the REMUS 6000) to unmanned surface vehicles (USVs), such as MARTAC’s MANTAS T12, and traditional crewed ships. At the heart of the system lies Teledyne’s phased-array transducer design, a field-swappable unit that enhances positioning accuracy, eliminating the need for speed of sound corrections, reducing vehicle drag, and supporting efficient contingency planning.
The Tasman’s versatility extends to navigation in open water when the seabed is out of range—a crucial feature for deep-sea research and oceanographic operations. It also excels when integrated with Inertial Navigation Systems (INS), offering real-time standard deviation and time of validity outputs for ultra-precise positioning. Designed as a drop-in replacement for the Workhorse Navigator, it streamlines, upgrades and minimises integration friction.
Operational resilience is further boosted with low-latency triggering, which avoids interference with other onboard sonars, and real-time health monitoring that provides advanced warnings of potential issues. For extended mission capabilities, the Tasman can be upgraded to include Acoustic Doppler Current Profiling (ADCP), making it invaluable for both scientific exploration and tactical operations.
Whether mapping the ocean floor, guiding autonomous fleets, or supporting complex marine missions, the Tasman DVL delivers uncompromising performance—meeting and exceeding expectations across scientific and operational domains.
