The instrument has many settings that allow you balance image quality and frame rate, depending on the application. (I.e. imaging mode has a slower frame rate, but a higher resolution).

|Cons=I think this is both a strength and a weakness: if you run into bandwidth issues, the M3 automatically slows its ping rate without giving a warning (or at least I haven't found the warning). There also isn't an exposed way to change the ping rate - the instrument automatically operates at the fastest ping rate possible for the selected settings. There is a workaround for this by either limiting the bandwidth or editing the instrument settings.

Kongsberg M3 Multibeam Echosounder

Manufacturer: Kongsberg
Measurement Category: Condition Monitoring, Location, Ship Monitoring, Animal Monitoring
Operating Environment: Underwater
Version(s): Depth ratings: 500 m and 4000 m
Basic, with sync, and VDSL options.
Mounting: Four 1/4-20 mounting holes
Communication Protocol: Ethernet
Operating Mode: Free Streaming
Power Supply Type: VDC
Power Specification: 12 - 36 VDC; 22 W typical



Description

The M3 Sonar is a 2D multibeam system with imaging and profiling capabilities. The M3 Sonar provides high-resolution and easy to interpret images by combining the rapid refresh rate of conventional multibeam sonar with image quality comparable to a single-beam sonar.


Instrument Measurements

  • Altitude (Position)
  • Bathymetry (Position)
  • Scour (External Environment)
  • Biofouling (External Environment)
  • Abundance (Animal Detection)
  • Individual (Animal Detection)
  • Presence (Animal Detection)
  • Behavior (Animal Identification)
  • Morphology (Animal Identification)
  • Depth (Animal Tracking)
  • Geodetic Position 2D (Animal Tracking)
  • Orientation (Animal Tracking)
  • Position (Animal Tracking)
  • Velocity (Animal Tracking)
  • Local Position less than 10km (Ship Tracking)
  • Trajectory (Ship Tracking)
  • Local Presence less than 10km (Ship Detection)

Measurement Specifications
Range: 0.2 m to 150 m
Range Resolution: 1 cm
Frequency: 500 kHz
Pulse Types: CW, CHIRP
Field of view, beamwidth, angular resolution, and update rate all depend on operational mode


Optional Sensors

No optional sensors provided. Please add sensors.


Notes, Considerations & Recommendations
