Basic characteristics:

  • Enhance your Revolution ROV's stability using a Doppler Velocity Log (DVL).

  • The DVL, combined with onboard sensors, improves your ROV's capability to combat current, maintain station, and control altitude above the seafloor.

  • The DVL offers an altitude range of 0.2 to 89 meters.

  • It provides precise Ultra-Short Baseline (USBL) positioning.

  • The DVL supports station keeping, enabling your ROV to maintain its position effectively.

  • With the DVL, your ROV can navigate more effectively, even in the presence of currents.

  • An auto altitude holding mode is available for altitude control.

  • The DVL mounts on the bottom of the Revolution, emitting four acoustic beams downward to calculate altitude (depth from the bottom) and estimate speed and direction of movement.

  • When combined with Deep Trekker BRIDGE sensor technology, the DVL provides more accurate and precise positioning and station holding, even in challenging current conditions.

Description

Pathfinder DVL 89M with Integration Kit Deep Trekker

Doppler velocity log for stabilization and autonomy on your Revolution ROV.

The DVL mounts on the bottom of the Revolution and sends four acoustic beams on angles downward. Reflections then calculate the altitude (depth from bottom) and provide an estimate of the speed and direction of movement. Combined with Deep Trekker BRIDGE sensor technology, the DVL provides more accurate and precise positioning and station holding - even in current.

  • DVL for search and recovery missions

During a search and recovery mission, the DVL will help maintain an optimal altitude for the imaging sonar, such as 15m above with the sonar on a 15 degree angle downward.

  • Position/Station holding with DVL

A DVL also is used to help hold position, say when performing an inspection and wanting to hold against current, or when using a manipulator or laser scanner where it is easier to be dead steady.

  • Automatic altitude hold

Use a DVL on the ROV to help stay on course in current, maintain an altitude above the sea floor. This is important for benthic surveys to get a clear picture without crashing into the bottom and stirring up sediment, making the survey more difficult.
