Quantum sensors for GPS-free orientation

Quantum sensors for GPS-free orientation

Along each of the three axes of measurement, a mechanical accelerometer is attached to the reference mirror of the atom interferometer, resulting in a classic/quantum hybridization that permits continuous measurement of acceleration with ultralow bias. Measurements of the three vector components are used to determine the acceleration vector, in any direction. The sensor is secured to a rotatable platform for demonstrating measurements from various angles. Credit: iXAtom

How can we navigate airliners or allow military vehicles to stay on course without GPS or satellite signals? This is a problem for which quantum inertial sensors offer a solution. Harnessing quantum technology, they can take ultrasensitive measurements of acceleration in three dimensions, and in any orientation.
