MIT Sends a Battery-Free GPS Underwater – News – All About Circuits
Researchers at MIT have developed a new underwater communication technique, called underwater backscattering localization, which they hope will need for batteries…
Based on RF communication, GPS devices communicates with satellites to determine their location via trilateration. Besides vehicle navigation, if there were ever an application that would benefit from GPS technology, it would marine travel.
