Dr. Gladys West, a mathematician who contributed to the development of GPS, has passed away at 95.

Dr. Gladys West: Rising from the Rural South

Gladys Mae Brown, born in 1930 in Virginia, overcame the challenges of segregation and poverty through education. Her academic excellence earned her a scholarship to Virginia State College, where she completed both her bachelor’s and master’s degrees in mathematics.

Dr. Gladys West: Unlocking the Science of Satellite GPS Navigation

In 1956, West, a mathematician at the U.S. Naval Proving Ground, programmed geodetic algorithms that enabled precise Earth mapping, crucial for modern GPS navigation.

Key Contributions & Legacy

• Mathematical Modeling of the Earth: In 1956, West became the second Black woman hired as a programmer at the Naval Surface Warfare Center Dahlgren Division (then the U.S. Naval Proving Ground). She programmed complex early computers, including the IBM 7030 Stretch, to model gravitational, tidal, and planetary forces.
• The Foundation of GPS: Her precise satellite geodesy calculations delivered the accurate geodetic Earth models that made satellite-based positioning, navigation, and timing reliable enough for modern GPS.
• Belated Recognition: Often celebrated as one of the real-world “hidden figures” of aerospace history, her vital role gained widespread public attention later in her life. She was inducted into the Air Force Space and Missile Pioneers Hall of Fame in 2018.
• Lifelong Learner: After retiring in 1998, West went on to earn her Ph.D. in public administration and policy affairs from Virginia Tech at age 70.

Despite her central role in creating modern digital navigation, she famously admitted with a laugh in later years that she still preferred paper maps when driving because she liked seeing the entire route laid out visually.

Triumphant Honors: Celebrating a Legacy Long Overdue

West’s contributions to aerospace and defense were hidden for most of her career due to military classifications. Her achievements gained recognition in retirement, leading to her induction into the Air Force Space and Missile Pioneers Hall of Fame and the Prince Philip Medal.

Enduring Truth: Purpose Outlasts Every Barrier

Dr. West’s journey exemplifies resilience, excellence, and dedication, illustrating the transformative power of perseverance against systemic challenges.

“Whatever your hand finds to do, do it with your might; for there is no work, nor device, nor knowledge, nor wisdom, in Sheol, where you are going.”

— Ecclesiastes 9:10 (WMB)

Dr. West applied her mind with all her might, mapping an uncertain globe so future generations could find their way. While she has completed her earthly journey, the digital constellations guiding humanity forward will forever carry the imprint of her brilliant mind.
