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.
- Currents
- Bottom track
Highlights
-
Bottom-track from 0.3-175 m range
-
Per-ping and per-beam data quality estimates
-
4000 m operational depth
Usage
-
Next-generation compact survey vehicles
-
Small vehicles requiring longer bottom track range in deep water
-
Compact AUVs with high accuracy requirements
-
Increase range of vehicles with existing DVL1000 without vehicle redesign
Integration
With the best balance of size and range in the survey-grade DVL market, the 6000m rated DVL500 Compact 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 Compact is compatible with top control software including EIVA, Seebyte and Greensea.
Reliability
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 assures thorough system level integration.
Results
The DVL500 Compact 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.
