At Sandia Labs, a vision for navigating when GPS goes dark

October 24, 2022 • ALBUQUERQUE, N.M. — Words like “tough” or “rugged” are rarely associated with a quantum inertial sensor. The remarkable scientific instrument can measure motion a thousand times more accurately than the devices that help navigate today’s missiles, aircraft and drones. But its delicate, table-sized array of components that includes a complex...
