DOPPLER VELOCITY LOG

DVL1000 - 4000 m

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

Highlights

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

Overview

  • 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.

Applications

  • Observation-class ROVs and AUVs
  • Near-bottom operations
  • Highly accurate subsea surveys
  • Easy integration with high-grade INS
