Intuitive Operator Control
Traditional imaging sonars rely on mechanical scanning to generate an image of the seafloor. The Omniscan 450 FS Imaging Sonar takes a completely different approach—it puts scanning in the hands of the ROV pilot.
Instead of waiting for a mechanical scanner to slowly sweep an area, the Omniscan 450 FS builds an image dynamically as the ROV moves. This means you can instantly focus on specific areas of interest. Cerulean’s SonarView software “paints” the image in real-time, giving pilots complete control over where and how they scan.
The result is excellent situational awareness in the murkiest conditions.
Performance
The Omniscan 450 FS offers a 120 meter range, allowing you to detect targets at these distances regardless of visibility. Its 50 degree vertical beam height ensures you can see objects far forward as well as below the ROV, even when operating high off the seafloor.
The Omniscan 450 FS helps you easily locate and approach targets, making it ideal for wreck hunting and navigation. It reveals details that other imaging sonars might overlook, and can assist in locating objects that are difficult to detect. Image quality is superior to multibeam forward looking sonars costing 10x more.
Doppler Mode
For ROVs without DVL motion information, Omniscan’s Dopper Position Tracking can be used for translational information along 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 with appropriate integration.

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.
