What
Quantum navigation uses cold-atom interferometers to measure a ship's acceleration and rotation relative to Earth's gravity and spin. It works by dropping clouds of ultra-cold atoms in a vacuum chamber and using lasers to measure how the ship's motion changes the atoms' quantum wave properties, allowing it to calculate position through dead reckoning without external satellite signals.Related FAQs: What does waterproof really mean for bike GPS trackers in real-world conditions?
