{wiki=Short_baseline_acoustic_positioning_system}
A Short Baseline Acoustic Positioning System (SBL) is a navigation technology used primarily in underwater environments, such as in marine and oceanographic research, underwater construction, and subsea operations. It utilizes sound waves transmitted underwater to determine the position of objects or vehicles, such as remotely operated vehicles (ROVs), autonomous underwater vehicles (AUVs), or divers. \#\#\# Key Components of SBL Systems: 1. **Transducers**: These are underwater devices that send and receive acoustic signals.
