Gladys west: the Hidden Figure Who Helped Build GPS
Gladys West, a pioneering mathematician whose groundbreaking work was instrumental in the growth of the Global Positioning System (GPS) we rely on today, passed away on January 17, 2026, at the age of 95 [1]. Her contributions,long unrecognized,have finally received the acknowledgement they deserve,cementing her legacy as a vital figure in modern technology.
Early Life and Education
Born Gladys Mae Brown in 1930 in rural Virginia, West demonstrated remarkable academic abilities from a young age. She excelled in school, earning a full scholarship to Virginia state College (now Virginia State University) where she majored in mathematics [2]. She graduated with a Bachelor of Science degree in mathematics in 1952 and later earned a Master of Mathematics in Engineering from Virginia state University in 1955.
A Career at the Dawn of Space Exploration
West began her professional career as a mathematics teacher in Virginia. However, the burgeoning space race and the need for skilled mathematicians led her to seek employment at the Naval Proving Ground in Dahlgren, Virginia, in 1956. This marked the beginning of a remarkable 42-year career with the U.S. Department of the Navy.
Developing the Mathematical Models for GPS
At Dahlgren, West was one of a small team of African American mathematicians – often referred to as ”human computers” – who performed complex calculations by hand. As computing technology advanced, she transitioned to programming computers. Her pivotal work involved developing complex algorithms to account for variations in gravitational forces and other factors that could affect the accuracy of satellite positioning.
Specifically, West played a crucial role in a 1978 project to model the Earth’s shape – known as the geoid – with greater precision. This was essential for accurate satellite positioning. Her refined geoid model ultimately became a key component of the GPS system [3]. Essentially, she helped create the mathematical foundation that allows GPS to pinpoint locations accurately.
Recognition and Legacy
for decades, West’s contributions remained largely unknown. It wasn’t until the early 2010s that her story began to gain wider recognition, thanks to a biography written by her granddaughter.In 2018, she was inducted into the Air Force Space and Missile Pioneers Hall of Fame, a testament to the profound impact of her work.
Gladys West’s story is a powerful example of the often-overlooked contributions of women and minorities in STEM fields. Her dedication, intelligence, and perseverance helped shape a technology that has become indispensable to modern life, from navigation and mapping to emergency services and countless other applications.
Key Takeaways
