Acoustic Positioning Systems

Acoustic Positioning Systems are technologies that use sound waves to determine the location of objects underwater, such as submarines, divers, or underwater vehicles. By sending acoustic signals and measuring how long it takes for these sounds to bounce back, the system calculates distances and positions. This method is essential in environments where GPS doesn't work, like under water. Essentially, it’s similar to how bats navigate using echolocation, allowing for precise tracking and mapping of underwater movements and installations.
