ONR-Guided Technology Tracks Assets Inside of Ships: "The Office of Naval Research (ONR) is funding emerging technology that will allow wireless surveillance not only of ships and aircraft, but also the tracking of people and high value assets inside the ships.
To help the Navy keep thorough tabs on its environment, ONR sponsors work in advanced electronics that ratchets up the Navy's ability to do just that. Precise At-Sea Ship System for Indoor-Outdoor Navigation (PASSION) enables wireless position tracking of both the external and internal environment of naval vessels."
