{wiki=Long_baseline_acoustic_positioning_system}
A Long Baseline Acoustic Positioning System (LBAP) is a navigation system used primarily in underwater environments to determine the position of an object, such as a submersible, underwater vehicle, or sonar device, relative to a reference point. The system operates using sound waves, which are a reliable means of communication and navigation in water due to their ability to travel long distances while being less susceptible to interference than electromagnetic waves.
