It's the Second Korean War of 2020, and things aren't looking good for the US-South Korean side. North Korea has used its jamming gear to disrupt low-power GPS signals accessible in South Korea for navigation. Luckily for Washington and Seoul, in 2013, the Pentagon's blue-sky researchers created a positioning tool for use when GPS goes down -- and even back then, it was smaller than a penny.
At the University of Michigan on Wednesday 10 April, researchers for Darpa announced they'd created a very small chip containing a timing and inertial measurement unit, or TIMU, that's as thick as a couple human hairs. When the satellites we rely on for navigation can't be reached -- whether they've been jammed or you're in a densely packed city -- the chip contains everything you'll need to figure out how to get from place to place. It's got gyroscopes, accelerometers and a master clock, to calculate orientation, acceleration and time.
