Highly accurate, Radar Responsive Tags have been tested by the US military for “Blue Force” tracking to avoid friendly fire.
Radar Responsive (RR) Tags were first developed at the US National Laboratories for the Department of Defense. Gentag, working with its partners, is making the civilian version of the original technology – the tags combined with sensors – available to the public. These small wireless chips can be read from miles away and provide exquisite geolocation capabilities, including for precise indoor geolocation.
Radar Responsive Tags, when combined with sensors in lightweight, noninvasive skin patches, have countless market opportunities, from tracking athletes at major sporting events, to geolocating medical equipment in large hospitals. Other applications include remote vital status monitoring and geolocation of Alzheimer’s patients, tracking firefighters in tall buildings, and monitoring small children. This technology can be entirely passive (battery-less).
