Gladys West, GPS Pioneer, Dies at 95: Remembering a Groundbreaking Mathematician

Dr. Gladys West, the brilliant mathematician whose work revolutionized navigation, has died at the age of 95. West’s impactful career saw her calculating precise models of the Earth’s shape at the Naval Surface Warfare Center, calculations that became the foundation for the Global Positioning System (GPS). Born in Virginia during the Great Depression, she triumphed over segregation to become a pioneering scientist. Her contributions to mathematics and technology have left an enduring legacy.

Earth’s Magnetic North Pole Shifts Toward Siberia, Requiring GPS Updates

A new World Magnetic Model (WMM) has been released, updating the location of magnetic north, which is now closer to Siberia. This update, necessary every five years to maintain GPS accuracy, reflects the magnetic pole’s unusual recent behavior: a period of unprecedented rapid drift followed by an equally unexpected slowdown. While a high-resolution model is available, most users will experience a seamless transition with standard WMM updates. The model’s accuracy was confirmed, projecting magnetic north’s position accurately through 2025.
