Mathematical modeling of the shape of the Earth served as the foundation for the modern Global Positioning System, a project driven by the complex computations of Gladys West. Beginning her career in the mid-1950s at the Naval Proving Ground in Dahlgren, Virginia, West provided the precise geodetic calculations necessary to ensure the accuracy of satellite-based navigation and mapping.
Early Education and Career Beginnings
Born in 1930 in Sutherland, Virginia, West pursued mathematics at Virginia State University after earning a scholarship as her high school valedictorian. Following her graduation in 1952 and the completion of a master's degree in 1955, she secured a position as a mathematician at the Naval Proving Ground in 1956. As one of only four black employees at the facility, she managed processing systems for satellite data analysis while concurrently earning a master's degree in public administration from the University of Oklahoma.

During the 1960s, West contributed to an award-winning study verifying the regularity of Pluto's motion. She later shifted her focus to satellite altimetry, working as a project manager for the Seasat program. Her core achievement involved programming the IBM 7030 Stretch computer to define the Earth's geoid. By accounting for gravitational and tidal forces, she created complex algorithms that allowed for highly accurate geopotential models. In 1986, she published the technical report detailing the data processing specifications for the Geosat satellite radar altimeter.
Professional Longevity and Recognition
West remained at the Naval Surface Warfare Center Dahlgren Division for 42 years, retiring in 1998. She later completed a PhD in Public Administration from Virginia Tech in 2000. Although much of her work remained classified for years, her influence on satellite geodesy eventually gained public notice. She was inducted into the United States Air Force Hall of Fame in 2018 and received the Prince Philip Medal in 2021. West died in Fredericksburg, Virginia, on January 17, 2026.
