This Unhackable Quantum Navigation System Is the Size of a Loaf of Bread

Q-CTRL has begun shipping compact quantum navigation systems to early customers for GPS-free positioning.

Its DBRN system uses magnetic-field mapping plus software correction to help resist jamming and spoofing.

The article says DBRN outperforms inertial navigation in tests.

A practical alternative to GPS could improve resilience for aviation, shipping, and military platforms in denied environments.
