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 as well as rotational. For underwater vehicles without positioning information, Omniscan's Dopper Position Tracking can be used for translational information in the direction of the beam. Using a pair of Omniscan 450 FS units, one forward and one 90 degrees to either side, full 2d motion tracking is available. This also enables position hold mode.

Operator Scanning

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.

Overall Dimmensions


Note 1: Far Field distance is the range beyond which the beam width specification is valid. At nearer distances the effective beam width gets wider, and sidelobes get larger. Note 2: This is the nominal theoretical 2-way (transmit and receive) 3dB beam width.
