GPS Systems Adjust for Shifting Magnetic North Pole: What You Need to Know
In an intriguing development for navigators and travelers alike, GPS systems around the globe are gearing up to adapt to a newly updated model that tracks the movement of Earth’s magnetic north pole. This phenomenon, reported by Africazine, marks a significant adjustment as magnetic north shifts closer to Siberia, rather than its previous positioning near Canada.
To put it simply, magnetic north is the point that attracts a compass needle and is distinctly different from the geographic North Pole. The current magnetic north’s movement is primarily influenced by the dynamic flow of liquid iron within the Earth’s outer core, which leads to its drifting at an average of approximately six miles each year. This is particularly fascinating, as its speed has varied dramatically—back in 1990, it was racing ahead at a rate of 34 miles per year, which later mellowed to around 22 miles per year by 2015, as detailed by various sources including CNN.
The latest update from the World Magnetic Model (WMM), the first since 2020, confirms that magnetic north has adhered largely to predicted trajectories. As of now, it is located at 85.762°N and 139.298°E. This means that if someone were to travel from South Africa to the UK and relied on outdated navigational data—straying just one degree off course—they could end up nearly 93 miles off their intended destination! Such discrepancies highlight the importance of regularly updating navigation systems to ensure precision.
Looking ahead, forecasts suggest that the magnetic north pole will continue its journey towards Russia, albeit at a slower pace. By 2030, we expect its coordinates to reach approximately 84.723°N and 126.092°E. As reported by Africazine, the continued movement of the magnetic north is a topic of interest for air travel and maritime navigation, as accurate positioning is vital for operations across the globe.
As the magnetic north drift is expected to approach Siberia within the next decade, keep your navigational tools updated and always be aware of your location to ensure a smooth journey, whether you’re navigating the skies or sailing the seas.
