MagNav System Uses Earth's Magnetic Field To Guide Aircraft
The US Defense Innovation Unit (DIU) has successfully tested a quantum-sensing navigation system, known as MagNav, which uses Earth’s magnetic field to guide aircraft without relying on GPS. The system, developed by Honeywell Aerospace, showed an 89% improvement in position accuracy during a recent flight test over the Pacific Ocean. This technology could provide an additional layer of resilience for both military and commercial aviation operating in GPS-denied environments, as reported by Unknown Source.
