An underwater navigation system powered by sound – MIT News
Underwater backscatter localization developed at MIT could allow for battery-free ocean exploration. The system is akin to subsea GPS and has potential applications…
GPS isnt waterproof. The navigation system depends on radio waves, which break down rapidly in liquids, including seawater. To track undersea objects like drones or whales, researchers rely on acoustic signaling. But devices that generate and send sound usually require batteries bulky, short-lived batteries that need regular changing. Could we do without them?
MIT researchers think so. Theyve built a battery-free pinpointing system dubbed Underwater Backscatter Localization (UBL). Rather than emitting…
