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.
S2CR 18/34 USBL with a horizontally omnidirectional transducer beam pattern is a universal tool for tracking and communication in reverberant shallow waters, providi
