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 AUV or ROV kilometers away with a 0.1 angle accuracy.
