Ultra Short Base Line (USBL) Positioning System for tracking ROVs
In open water applications where you want to know exactly where you are and where you are going, use this positioning system to track your ROV.
Using a dunking transducer at the surface and a transponder mounted to the top of the ROV, the two communicate using acoustics. The relative position of the ROV to the dunking transducer is calculated and then through Bridge software is displayed on a Google Map on your controller.
Allowing you to visualize your ROV position during the dive and plot points of interest.
Track and Log Data
Ocean Science ROV operators historically use USBL to track where they saw certain features and log data over the span of their dive.
Inspection companies inspecting critical infrastructure use the USBL to log where they find defects and anomalies during an inspection.
