"Teledyne RDI Workhorse Navigator 150 kHz Doppler Velocity Log and current profiler"@en . . "SDN:L22::TOOL0372" . "A Doppler velocity log (DVL) measuring bottom track and water track velocities, altitude, heading, tilt, temperature, echo intensity and current velocities. 150kHz Broadband signal processing gives high data resolution and a four-beam solution gives an independent error velocity measurement as an indicator of data quality. It has a bottom track range of 400m and velocity accuracy for both bottom and water track modes is 0.4% of the velocity, ±0.2cm/s. The instrument operates effectively over a temperature range of -5°C to 45°C and with a tilt of up to ±15 deg."@en . .
