Long Baseline (LBL) Systems
Teledyne Benthos offers a full line of subsea acoustic communication based products that can be configured in many different ways, including into Long Baseline (LBL) positioning systems.
Benthos modems and acoustic releases can be set up as transponder nodes, either fixed or mobile, that can be used to calculate range between any one node and the others. The distance between the transponders is usually hundreds, if not thousands, of meters, hence the name Long Baseline. With the inclusion of telemetry, a network can adapt to changing transponder positions to provide greater operational flexibility.
