New centimeter-accurate GPS system could transform virtual reality and mobile devices

The new system could allow unmanned aerial vehicles to deliver packages to a specific 

spot on a consumer's back porch, enable collision avoidance technologies on cars and 

allow virtual reality (VR) headsets to be used outdoors

Researchers in the Cockrell School of Engineering at The University of Texas at Austin have developed a centimeter-accurate GPS-based positioning system that could revolutionize geolocation on virtual reality headsets, cellphones and other technologies, making global positioning and orientation far more precise than what is currently available on a mobile device
