sonar navigation
Sound-based underwater guidance
Sonar navigation uses sound waves to determine position and detect obstacles underwater.
A device emits pulses that bounce off surfaces and return; the time delay reveals distance and direction.
Submarines, ships, and marine animals like dolphins rely on sonar to navigate where light cannot penetrate: The submarine used sonar navigation to thread through the underwater canyon.
