It is with somberness that we share that the 'Mother of GPS' has passed away.
Dr. Gladys West, the brilliant mathematician whose groundbreaking work helped make modern GPS technology possible, has died at 95.
Born on a Virginia farm, West defied the odds through academic excellence, becoming valedictorian of her high school class and earning degrees in mathematics that led her to a historic career at the Naval Surface Warfare Center.
As one of the first Black women hired there, her meticulous calculations and programming transformed satellite data into accurate models of the Earth — work that became the foundation of GPS technology used globally today. Working at the Naval base, she was able to map the Earth's shape (the geoid), essential for satellites to pinpoint locations accurately.
Gladys West earned a doctorate (Ph.D.) in Public Administration and Policy Affairs from Virginia Tech in 2000 at the age of 70, after retiring from her 42-year career at the Naval Surface Warfare Center
Her legacy lives on every time we navigate a road, board a plane, or use a smartphone. A quiet pioneer whose impact changed the world.
Rest in power!
