MIT has developed a new navigation system designed for use underwater that could do for underwater wayfinding what GPS has done for travel on and above the surface. GPS doesn’t really penetrate underwater, because radio waves aren’t really water-friendly. It’s why you commonly see things like sonar employed on submarines, which emit sound waves and […]
