Description

The Omniscan 450 FS is ideally suited for forward-looking ROV applications. The transducer and electronics are housed in a single enclosure with an Ethernet + power interface. Two enclosure options are available for a 100m or 300m depth rating.

As the ROV or surface vessel moves, Cerulean SonarView “paints” the image of the scanned area of the sea floor giving excellent situational awareness in the murkiest conditions.

In the case of a surface vessel with GPS or an ROV with DVL, scanning is translational and rotational. For underwater vehicles without positioning information, Omniscan’s Dopper Position Tracking can be used for translational details in the direction of the beam. A pair of Omniscan 450 FS units, one forward and one 90 degrees to either side, will be used, and full 2d motion tracking will be available. This also enables position hold mode.Using Omniscan 450 FS on an ROV, the scanning is under the direct control of the ROV driver so that they can focus on specific areas of interest rather than waiting for a mechanical scanning sonar to slowly come around to sweep the particular sector they want to see. Using the “Heading Up” mode in SonarView makes this manual scanning very intuitive and provides excellent situational awareness.
