Speck of Glass Holds Seven Electronic Devices
In a pellet of glass the size of an apple seed, Univ. of Michigan engineering researchers have packed seven devices that together could potentially provide navigation in the absence of the satellite-based Global Positioning System (GPS.)
Space-based GPS – convenient for civilians and essential for the military – is far from fail-proof. It doesn’t work indoors, near tall buildings or in heavy cloud cover, and it’s relatively easy to jam, researchers say.
