**Boeing Completes First In-Flight Test of Quantum Navigation System**

Boeing has successfully conducted the world’s first flight test of a quantum navigation system, operating without GPS for four hours aboard a Beechcraft 1900D. The test used a six-axis quantum inertial measurement unit (IMU) developed with AOSense, which demonstrated precise navigation performance during takeoff, flight maneuvers, and landing.

The IMU uses atom interferometry to detect acceleration and rotation via atoms, enabling high-precision tracking without GPS reliance. The system could reduce long-flight navigation errors from kilometers to mere meters.

Additional tests included Boeing’s All Source Positioning, Navigation and Timing (ASPNT) software, a star tracker developed with HRL Laboratories, and AQNav, a quantum magnetometer system from SandboxAQ. These technologies support accurate, unjammable navigation in GPS-denied environments.

Boeing will continue lab testing to optimize the system’s environmental performance and reliability.
