DVL1000 - 4000 m

Bottom-track from over 0.2 to 75 m range; 4000 m max. operational depth

  • Industry-wide acceptance
  • Bottom track from 0.2-75 m range
  • Quality estimates - per beam and ping


The DVL1000 is the world’s smallest survey-grade Doppler Velocity Log. It combines compact design with unprecedented functionality, being able to fly higher in the water column and closer to the seabed than similar equipment. It has a maximum operational depth of 4000 m and is ideally suited for subsea navigation where size and weight are a concern. This 1 MHz Doppler Velocity Log is used by industry leaders in the subsea market because of its high accuracy and state-of-the-art technology.

  • Bottom track


  • Industry-wide acceptance
  • Bottom track from 0.2-75 m range
  • Quality estimates - per beam and ping


  • Integration on observation-class ROVs and AUVs
  • Near-bottom operations in deep-sea areas
  • Precision navigation for highly accurate subsea surveys


This 4000m rated survey-grade DVL is equipped for easy integration with leading INS systems to create a robust, reliable navigation system, tested and proven across AUV, ROV, USV and other platforms of all sizes. As with all of Nortek's DVLs, the DVL1000 is compatible with top control software including EIVA, Seebyte and Greensea.


Tested in demanding conditions in the Oslo fjord, the DVL1000 has a proven track record in areas of variable bathymetry and conditions. The water track feature provides a velocity backup if the bottom becomes out of range. The spectrum analyzer assures thorough system level integration.


The DVL1000 provides reliable navigation in the most demanding conditions across multiple platforms. The addition of simultaneous current profiles improves operational safety and allows opportunistic oceanographic data collection.
