Highlights

  • Bottom-track from 0.3-175 m range
  • Per-ping and per-beam data quality estimates
  • 4000 m operational depth

Overview

  • The DVL500-Compact combines the compact design of the standard DVL1000 with the superior bottom-track range of the DVL500. It can fly higher in the water column and closer to the seabed than similar equipment, enabling small vehicles to do bigger jobs.

Applications

  • Small vehicles requiring longer bottom-track range
  • Compact AUVs with high accuracy requirements
  • Easy integration with leading inertial navigation systems (INS)
