Kongsberg M3 Sonar for Teledyne Seabotix ROV

Teledyne Seabotix has integrated its vLBV observation class remotely operated vehicle (ROV) with Kongsberg M3 sonar system.

The M3 sonar is a 2D multibeam system which provides high-resolution images by combining the rapid refresh rate of conventional multibeam sonar with image quality comparable to a single-beam sonar, Kongsberg explained.

The new M3 sonar integration package developed by Teledyne Seabotix enables detection of small objects at distances of more than 150 meters combined with a 120° to 140° field of view, allowing the operator to see the complete underwater picture in real-time.

The M3 Sonar includes two distinct transmitters. The eIQ enhanced image quality transmitter operates at 500 kHz and provides clear images well past 150m range. The VVBT variable vertical beam-width transducer allows the operator to reduce the across-path beam height from 30 degrees to 15 degrees and even 7.5 degrees, to reduce surface returns in images.

The VVBT transducer generates point cloud data that integrates with Hypack and Qinsy software.

The integration package includes flotation and trim weights to adjust trim of the vLBV with the M3 sonar installed.
