DVL500 Compact, Schilling

6000 m

Tracking du fond de 0.3 à 200 m. Opérationnel jusqu'à 6000 m


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, and maximum operational depth is 6000 m. 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

Points forts

  • Bottom track from 0.3-200 m range
  • Per-ping and per-beam data quality estimates
  • 6000 m operational depth


  • Highly accurate subsea surveys
  • AUVs with long missions or high accuracy requirements
  • Easy integration with leading inertial navigation systems (INS)


Equipped with a Seanet connector, this version of the DVL500 Compact is designed for seamless integration with TechnipFMC Schilling Robotics ROVs.


Tested in demanding conditions in the Oslo fjord, the DVL500 Compact 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 ensures performance.


Effortless setup with dropdown menu initialization significantly reduces integration time, getting jobs up and running faster.
