NavQuest Doppler Velocity Logs
Doppler velocity logs for precision navigation of AUVs, ROVs, manned submersibles and divers, depth rated to 6000 m.
Description
NavQuest Doppler velocity logs (DVLs) provide fast, accurate velocity output with long range and small minimum altitude for underwater vehicle navigation. Launched commercially in late 2006, they integrate with LinkQuest TrackLink USBL and PinPoint LBL systems. Model P versions offer higher accuracy.
Models
- NavQuest 600 Micro: altitude up to 110 m, minimum 0.3 m, accuracy 1% +/- 1 mm/s; about 12.6 cm diameter, 17.0 cm long, under 1.2 kg in water
- NavQuest 600: altitude up to 140 m, minimum 0.3 m, 600 kHz
- NavQuest 300: altitude up to 300 m, minimum 0.6 m, 300 kHz
Applications
Deepwater and shallow water AUV navigation, ROV station keeping and monitoring, and navigation of manned submersibles and divers.
