snip-ALEXANDRIA, VA — Dr. Gladys West, the pioneering mathematician whose work laid the foundation for modern GPS technology, has died. She passed away Saturday, surrounded by her loving family. She was 95."


snip-"In 1956, West began working as a mathematician at the Naval Surface Warfare Center in Dahlgren, Virginia. She was only the second African American woman hired at the base and one of just four African American employees at the time. What followed was a career that would quietly change the world."



snip-"At Dahlgren, West devoted herself to solving one of science’s most complex challenges: accurately modeling the shape of the Earth. Her painstaking calculations and programming helped transform raw satellite data into precise geodetic models, enabling reliable satellite-based navigation. That work ultimately became the backbone of the Global Positioning System (GPS) — now essential to aviation, shipping, emergency response, smartphones, and daily life worldwide."
