Navigation sensor package

DVL500 - 300 m kopi

A sensor hub that makes vehicle control and navigation possible.


  • Small size
  • Complete sensor suite
  • Proven performance


  • 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.


  • Small ROV
  • Micro AUV
  • Coastal USV
