Доплеровский лаг

600 kHz and 300 kHz deep water hydroacoustic Doppler logs contain the built-in echo sounder. Logs are used to measure the horizontal components of carrier movement velocity relating to the bottom and relating to the layer of water.

Logs can also be used as Doppler flow velocity profilers.

Installed on underwater vehicles of various types (towed, remotely-operated and autonomous), on the fixed and mobile buoy stations, ships of various projects. Used as an integral part of marine navigation systems or as a standalone tool for scientific research.

THE SHIP’S HYDROACOUSTIC DOPPLER LOG WITH THE FEATURE OF FLOW VELOCITY PROFILING

Доплеровский лаг

FEATURES:

  • Deep water realization
  • The “planar frame” antenna design type makes it easy to mount to the vessel bottom
  • Built-in sensors of careen, trim difference and magnetic course
  • Averaging time for profiling mode regulated by the user
  • Best-in-class layers resolution capability
  • Information providing related to the intensity of received acoustic signals

Used for installation on ships and underwater vessels of different projects. Used for navigation tasks, ecological monitoring, climate controlling, research in the field of fishery, in underwater cable routes lying. The maximum range is 1200 m. Depth is up to 6000 m. The ship’s Doppler log consists of two antenna arrays and electronic unit.

The log has two modes: the navigation mode and the flow velocities profiling mode. The measurement of the horizontal components of the carrier velocity relation to the bottom and relation to the water is provided in navigation mode.

The measurement of the vertical profile of flow velocity in layers with the specified size of the layer, obtained values can be given in the instrument coordinate system and the earth axis system is provided in profiling mode.
