Navigation

DVL500 - 6000 m

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

Aperçu

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

Utilisation

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

Integration

This high-performance, 300m 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. As with all of Nortek's DVLs, the DVL500 is compatible with top control software including EIVA, Seebyte and Greensea.

Reliability

Tested in demanding conditions in the Oslo fjord, the DVL500 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.

Results

The DVL500 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.
