Cerulean Omniscan 450 FS Sonar for Chasing Underwater Drones

Chasing Cerulean Omniscan sonar The Omniscan 450 FS is ideally suited for forward looking ROV applications. The transducer and electronics are housed in a single enclosure with Ethernet + power interface. Two enclosure options are available for 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 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. The Omniscan 450 comes in two models, the FS (forward scanning), and SS (side scanning). This manual covers both models. Note that although the model designations indicate Forward and Side scanning, in reality either one can be used for either application. The real difference is in the transducer and the packaging. The Omniscan 450 FS pictured below is fully packaged in its own enclosure housing the transducer and the electronics module. 100m and 300m enclosures are available.

Examples: 10 pps @ 50m, 5 pps @ 140m range setting Power Supply 10-30 Volts, 5 watts max at idle, 10 watts max while pinging Data Interface 100BaseT Ethernet Electrical Connection Single cable with 4 pin JST for data (Blue Robotics Ethernet standard), plus a wire pair for power. Adapter provided for standard RJ-45 ethernet connection. Maximum Range 100m Far Field (Note 1) 7m Beam Width (Note 2) 0.8° Beam Height 50° Maximum Operating Depth 100m and 300m versions Weight in Air 440g(100m), 825g(300m) Weight in Water -60g(100m), +325(300m) Overall Dimensions 55x67x200mm  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.   WHAT'S IN THE BOX? *Omniscan (100m or 300m) with Ethernet *Power Wiring Cable *Blue Robotics RJ45 to JST GH Adapter
