Geolocation and situational awareness is paramount in emergencies and incident management. Today, GPS is used to provide that awareness outdoors with some success. Indoor location requires horizontal accuracy, vertical accuracy, the ability to operate in the absence of power and withstand extreme weather conditions, and ubiquity and consistency.

A new breed of global navigation satellite signals will give the next generation of smartphones 30-centimeter accuracy instead of today’s 5 meters. Even better, the chip works in a city’s concrete canyons, and it consumes half the power of today’s generation of chips.  Read article here: https://spectrum.ieee.org/tech-talk/semiconductors/design/superaccurate-gps-chips-coming-to-smartphones-in-2018
