Ultra-Short Baseline and Super-Short Base Line is a method of underwater acoustic positioning. A USBL transmits an acoustic pulse which is detected by a transceiver and converted into a range. With both range and distance measurements, a USBL or SSBL is able to position an [AUVs - Autonomous Underwater Vehicles] or [ROVs - Remotely Operated Underwater Vehicles] kilometers away with a 0.1 angle accuracy.
This is the portable member of the world's most successful SSBL (USBL) systems in the HiPAP family. Operates also LBL and high speed acoustic link.
High-speed device for short- and medium-range applications, wide-angle beam pattern for communication in vertical, slant and horizontal channels
