Aging Earth magnetic field data could hit navigation for aircraft and drones

Warnings are growing that navigation accuracy for aircraft and drones could be disrupted as reference data used by electronic compasses ages quickly. Electronic compasses rely on Earth magnetic field models, unlike GPS, and the World Magnetic Model underpins compass functions in most devices. Earth’s magnetic field is constantly changing, shortening model validity. Concerns are also rising that an end to ESA’s Swarm mission could weaken data reliability, prompting U.S. efforts to develop near real-time magnetic sensing technology.
