Acoustic Navigation

Acoustic navigation uses sound waves to determine the position and movement of objects underwater, where GPS signals can't reach. Devices emit sound pulses that travel through the water, reflect off objects or seafloor features, and return as echoes. By measuring the time it takes for these echoes to return, the system calculates distances. This technology is essential for submarines, underwater robots, and maritime navigation, providing accurate positioning even in the depths of the ocean. It leverages the predictable behavior of sound underwater, allowing for precise and reliable navigation where traditional methods are ineffective.
