DARPA Developing Alternative to GPS; Doesn’t Depend on Satellites
April 25th, 2013Via: AFP:
To that end, researchers at DARPA and the University of Michigan have created a new system that works without satellites to determine position, time and direction, all contained within a eight-cubic-millimeter chip.
The tiny chip holds three gyroscopes, three accelerometers and an atomic clock, which, together, work as an autonomous navigation system.
DARPA envisages using this technology to replace GPS in some contexts, especially in small-caliber ammunition or for monitoring people.
