Teledyne RDI’s Tasman DVL is a next-generation Doppler velocity log engineered to deliver reliable motion sensing and positioning for subsea platforms operating in demanding marine environments.
Designed as a successor to legacy navigation instruments, it combines a reduced form factor with extended tracking capability, supporting bottom-lock measurements from very close proximity to long-range operation in depths reaching 6,000 meters. The system is suited for integration across remotely operated vehicles, autonomous underwater vehicles, and other subsea assets requiring consistent velocity data for navigation and control.
A phased array transducer architecture underpins the system’s performance, improving positional fidelity while minimizing sensitivity to environmental variables such as sound speed variation and marine growth.
The unit supports Ethernet connectivity for modern data workflows and enables concurrent data streaming via multiple protocols. Additional functionality includes field-replaceable transducer elements, onboard health monitoring with leak detection, and upgradeability for current profiling measurements. Low-latency triggering and dynamic command handling allow seamless operation alongside other acoustic systems, supporting tightly coupled inertial navigation solutions.
