Biography
Gladys West is a groundbreaking mathematician whose work on satellite geodesy at the Naval Weapons Laboratory formed the mathematical foundation for GPS technology. Her precise computational models of Earth's shape and gravitational fields revolutionized navigation and positioning systems used globally. Largely unrecognized for decades, West's contributions became celebrated when she was inducted into the US Air Force Hall of Fame in 2018.
