Underwater tracking system SBL - Short Base Line
Shark Marine Technologies
SBL Provides accuracy in the range of 10 metre in varying conditions. The transducers are mounted on the surface vessel and the underwater vessel, therefore the position is relative to the surface vessel. The addition of a DGPS and Compass will allow for geodetic positioning. SBL is less expensive than LBL and is favoured when positioning is not as critical or when live boating.
