Subsea Positioning (Fall Draft)

Cost effective ROV positioning systems enabling explorers, researchers, and search & recovery around the world.

Subsea Positioning Family

The Cerulean subsea positioning products include the Tracker 650 DVL the ROV Locator USBL and the flagship Omnitrack USBL featuring integrate top side deployment frame with integrated GNSS compass. All products are fully supported with the Cerulean SonarView application.

All Omniscan and ROV Locator (ROVL) products feature a pinging device on the ROV (or other subsea asset) and a USBL (ultra short baseline) receive array on the top side to detect the 3 dimensional direction to the ROV. The time that the ping arrives at the top side USBL sensor determines the distance to the ROV.

Omnitrack and ROVL families differ in that Omnitrack is a full top side assembly with GNSS compass ready to deploy. ROVL is a lower cost solution for applications where magnetic compass calibration is not an issue and magnetic heading accuracy is not as important. The different models within the Omnitrack and ROV Locator families differ in how they maintain timing synchronization between the ROV and the top side.

Tracker 650 DVL can be used independently or as a supplement to a USBL system to provide high update rate velocity information for smooth seamless tracking of your ROV subsea position.

Omnitrack USBL

Omnitrack is the flagship family of the Cerulean subsea positioning product line. Superior accuracy with no calibration required, free from magnetic interference, and simple deployment from a boat or pier. Omnitrack comes in tethered or wi-fi versions, ring float or BlueBoat floatation, and choice of networked or traditional duplex acoustic synchronization.

ROV Locator USBL

The ROV Locator (ROVL) family includes the popular and low cost Mk II, the simpler-to-use Mk III, and the latest Mk V.

The three versions differ in how the ROV and top side components achieve timing synchronization with various trade-offs of ease-of-use and cost depending on the application.

Tracker 650 DVL

Tracker 650 DVL is a great upgrade to any Omnitrack or ROVL subsea positioning systems. Whereas the USBL position updates are only once per second, the Tracker 650 provides high update rate velocity information so that SonarView can fuse the data to give seamless smooth motion tracking. On MAVLink/Ardusub based ROVs seamless fusing is provided directly by the vehicle so is available even without SonarView.
