US military developing geolocation system for underground
DARPA envisions a future in which U.S. Special Forces or spooks have to assault underground bases. And the Pentagon agency wants to give those warriors an underground navigation system that works on lightning bolts, The Register reports. The Global Positioning System (GPS) has transformed how both the military and civilians get around, courtesy of a satellite network that can triangulate a person's position on an interactive navigation map. But such a system only works on the Earth's surface, and so it's useless for military or intelligence operatives who need to infiltrate underground lairs. That dilemma prompted DARPA to launch its "Sferics-Based Underground Geolocation" project, known more colloquially as S-BUG. The idea involves harnessing low-frequency radio signals or pulses created naturally by lightning strikes, because such signals can penetrate deep underground. An underground receiver carried by warfighters or spooks might receive info on lightning strikes from a surface base station
