Subsea navigation

DVL500 - 300 m kopi

A sensor hub that makes vehicle control and navigation possible.

Overview

The DVL500 is a universal Doppler Velocity Log that combines compact design with unprecedented functionality. It can fly higher in the water column and closer to the seabed than similar equipment. This 500 kHz Doppler Velocity Log is used by industry leaders in the subsea market because of its high accuracy and state-of-the-art technology.

  • Currents
  • Bottom track
  • Altimeter

Highlights

  • Small size
  • Complete sensor suite
  • Proven performance

Usage

  • Small ROV
  • Micro AUV
  • Coastal USV

Integration

Unlike typical DVLs, the 300m rated Nucleus1000 is equipped with a pre-calibrated and pre-synchronized AHRS, temperature and pressure sensors, bringing users closer to true navigation while greatly reducing integration work. For those requiring a full positioning solution, the Nucleus can be provided with an optional INS firmware feature.

Reliability

The Nucleus1000 provides many of the features of a Nortek DVL, including water track in case of bottom track loss, rigorous testing in the demanding conditions of the Oslo fjord, and multiple data quality checks, all in a compact package.

Results

Integration of a guidance and navigation system on small vehicles becomes achievable, effective, and affordable with the Nucleus1000, enabling those vehicles to perform longer and more efficient missions. The Nucleus1000 software provides visualization of outputs and sense-checks of sensors, including a 3D visualization of the sensor’s AHRS.
