Gladys Mae West: The Hidden Genius Behind GPS Technology

06 DEC 2024

Gladys Mae West, was an American mathematician known for her contributions to the mathematical modelling of the shape of the Earth, she was one of the team of mathematicians who worked on the development of the satellite geodesy models that were eventually incorporated into the Global Positioning System. Today in 2018, she was inducted into the Air Force Space and Missile Pioneers Hall of Fame.

In the pantheon of unsung heroes whose contributions have profoundly influenced modern technology, Gladys Mae West stands as a beacon of mathematical brilliance and perseverance. A trailblazing American mathematician, her work on satellite geodesy models was instrumental in developing the Global Positioning System (GPS), a technology that has transformed navigation and location-based services worldwide.

Born in 1930 in Sutherland, Virginia, Gladys Mae West grew up in a rural community during the era of segregation. Despite the socioeconomic challenges of her time, she excelled in academics, recognizing education as her pathway to a better future. She earned a scholarship to Virginia State College (now Virginia State University), a historically Black college, where she majored in mathematics. West graduated as valedictorian of her class, demonstrating not only her academic prowess but also her determination to break barriers. After graduation, Gladys West began her career as a teacher before transitioning to work at the U.S. Naval Proving Ground in Dahlgren, Virginia (now the Naval Surface Warfare Center) in 1956. She was one of only four Black employees at the facility. Her work initially involved programming and managing large-scale computers, which were then cutting-edge technology.

West's expertise in mathematics and computing soon led her to contribute to the study of satellite geodesy—the precise measurement of Earth's size and shape. Her meticulous calculations and data analysis laid the groundwork for developing accurate geodetic models of the Earth. These models, which account for variations in Earth's shape due to gravitational, rotational, and topographical forces, were critical for the development of GPS technology.

One of her significant contributions was refining the accuracy of satellite data, ensuring that GPS systems could provide precise location information. Her work, spanning decades, combined rigorous mathematics, advanced computing, and innovative problem-solving. Despite her pivotal contributions, Gladys West's work remained largely unrecognized for many years. However, in 2018, she received long-overdue recognition when she was inducted into the Air Force Space and Missile Pioneers Hall of Fame. This honor celebrated her groundbreaking achievements and placed her among the elite contributors to space and satellite technology.

Her induction was not just a personal accolade but also a testament to the critical role of women and minorities in advancing STEM fields. Gladys West’s story has since inspired countless individuals, particularly women of color, to pursue careers in mathematics, science, and technology.

In addition to her professional achievements, Gladys West exemplifies the spirit of lifelong learning. She earned her Ph.D. in Public Administration from Virginia Tech in 2004, further solidifying her commitment to education and intellectual growth.

Today, GPS is an indispensable technology used in navigation, mapping, telecommunications, disaster management, and even precision agriculture. Every time a driver relies on their smartphone to find directions, or a search-and-rescue operation uses GPS to locate someone in need, Gladys West’s legacy is at work. Her mathematical contributions continue to shape the modern world in ways few could have imagined during her early career.

Gladys Mae West's journey from a small rural community to becoming a global pioneer in technology is a story of resilience, intellect, and determination. Her groundbreaking work in geodesy and GPS technology underscores the transformative power of mathematics and the importance of diversity in STEM fields. As we navigate our interconnected world, her contributions remind us of the quiet but profound impact of individuals dedicated to advancing human knowledge.
