Operation principle

Operation principle

Operation principle

• Software to process INS/GPS data to provide position and orientation of the UHV

• Software to process the Ultrasonic data acquired from UHV and transform them into a Geo-reference frame that can be used for multi-purpose– water-floor mapping– Detecting underwater object– Monitoring underwater infrastructure
