Researchers from NASA’s Jet Propulsion Laboratory have developed a system called POINTER (Precision Outdoor and Indoor Navigation and Tracking for Emergency Responders) that could save firefighters’ lives.
GPS technology and radios work well for outdoor tracking, but finding a firefighter in trouble inside a large building defeats known technology at this time. POINTER, which uses quasistatic fields instead of the currently used radio waves, may solve this problem, reports Andrew Good of NASA.
