USBL Application :
USBL (ultra-short baseline, also sometimes known as SSBL for “Super Short Base Line”) is a method of underwater acoustic positioning. It is used to track subsea targets such as ROVs/AUVs or divers. It can also be used as a mean of position referencing for surface vessels Dynamic Positioning (DP).USBL positioning is used from shallow to deep waters (down to 10,000m and more) and its accuracy is proportional to the distance, typical from 1-2% of the slant distance for basic equipment and up to 0.06% for the ultimate USBL systems.
