Sonardyne Scout Plus USBL

Scout USBL is a complete vessel based acoustic positioning system designed for tracking divers, ROVs and towfish in waters up to 1,000 metres. The system calculates the position of a subsea target by measuring the range (distance) and bearing (heading) from a vessel mounted transceiver to a small acoustic transponder fitted to the target; a technique known as Ultra-Short BaseLine (USBL) positioning. USBL is widely used by the offshore survey and ocean scientific industries as it offers high accuracy performance combined with efficient subsea tracking operations.
