Tasman DVL

Key Features:

Phased Array: Unique phased array transducer design delivers enhanced position accuracy at a reduced size, eliminates the need for speed of sound correction, and reduces susceptibility to biofouling.
Cost Saving: Field swappable phased array transducers
Versatile: Upgradeable to include Acoustic Doppler Current Profiling capability.
Ethernet Compatible: Plug-n-play with today's interfaces.
Extended Range: Optional XRT (Extended Range Tracking) delivers up to a 60% increase in bottom tracking range
Simultaneous Multiple Data Type Output Capability: Ethernet interface allows for simultaneous multiple PD data output via TCP and/or UDP.
Dynamic Commands Capability: Pathfinder accepts command changes during operation without the need to stop the ping cycle or operation of the DVL.
Bottom-Track High Resolution Velocity and Navigation Parameters Data Blocks: Aid in the velocity measurement resolution and quality information for use in an Ex-tended Kalman Filter (EKF) Inertial Navigation System (INS) solution.
Time of Validity Output: Delivers highly accurate coupling with an INS further improving resulting DVL aided INS position accuracy.
Low Latency Trigger: Mitigates interference with other SONARs
Leak Detection and Health Monitoring: Provides early warning for potential issues
