SONAR / ACOUSTIC IMAGING

Omniscan 450 FS

Navigation support when the camera is not enough.

Cerulean forward-looking sonar for observing the environment ahead of the ROV, including in poor visibility.

THE SYSTEM IN PRACTICE

How it fits
your work.

Omniscan FS acoustically observes the area ahead of the vehicle. The scan is built through sensor movement: it should not be confused with an instantaneous forward-looking multibeam image.

In turbid water it can complement optical imaging. ROV mounting, orientation and movement must support data interpretation in SonarView. The 100 m and 300 m variants have different nominal depth ratings.

Forward observation

Scanning the environment ahead of the vehicle.

Piloting support

Useful information when optical visibility is limited.

System integration

Can be paired with a DVL and SonarView display.

CONFIGURATIONS, EQUIPMENT AND DATA

A closer look.

Scanning and vehicle movement

The sensor follows forward, reverse, lateral and rotational ROV movement. Forward and side scanning are observation and navigation tools with different geometries. Configuration photographs include ten-thruster ROVs, dual FS units and SonarView displays.
