Meet Dr Gladys West

Gladys Mae West is an American mathematician and is often called the “Hidden Figure” behind the GPS system used in maps and navigation today.
U.S. Navy

West won a full-ride scholarship to Virginia State University, where she decided to major in Mathematics. Following graduation, she taught Maths and Science before returning to Virginia State University to undertake a Masters in Mathematics. After another brief teaching stint, she was hired by the US Naval Weapons Laboratory, where she worked as a Programmer and Project Manager of analysing satellite data using data processing systems.

Following her participation in an award-winning study regarding the regularity of Pluto’s motion relative to Neptune, West put together mathematical models of the shape of the Earth by analysing data from satellites. She project-managed the first-ever satellite that could remotely sense ocean positions. She continued her own work in modelling the shape of the Earth (a field known as geodesy) and her calculations became more and more precise. Her algorithms utilised huge amounts of data to account for variations in different forces that distort the Earth’s shape, such as gravitational and tidal forces. The data that West used in this modelling became the basis for the Global Positioning System – now known worldwide as GPS, and is utilised in fields as distinct as astronomy, navigation, sport, robotics, emergency services, clock synchronisation and self-driving cars.

Inside GNSS

Dr Gladys West is inducted into the Air Force Space and Missile Pioneers Hall of Fame during a ceremony in her honour at the Pentagon in Washington, D.C., on December 6, 2018. West was among the so-called “Hidden Figures” part of the team who did computing for the U.S. military in the era before electronic systems. The Air Force Space and Missile Pioneers Hall of Fame is one of Air Force’s Space Commands Highest Honors.

A Mighty Girl

Following 42 years of working at Dahlgren, West retired in 1998. Following this, she undertook a PhD at Virginia Tech in Public Administration. Her achievements weren’t recognised until she submitted a short biography for an alumni function at her undergraduate sorority, Alpha Kappa Alpha. She was inducted into the United States Air Force Hall of Fame in 2018 as a result of her work and its longstanding applications.
