Acoustic positioning

Acoustic positioning is a method used to determine the location of objects underwater by using sound waves. Devices called transponders or beacons emit or reflect acoustic signals, which are detected by receivers or acoustic antennas. By measuring the time it takes for these signals to travel between the objects and the receivers, a system can calculate precise positions. This technique is essential for submersibles, underwater robots, and marine research, as radio waves don’t work well underwater. Acoustic positioning provides accurate spatial data critical for navigation, exploration, and mapping beneath the surface.
