Gladys West, Mathematician Whose Work Underpinned GPS, Dies at 95

Her geodetic models at the Navy’s Dahlgren center provided the precision that enabled modern satellite navigation.

Overview

  • Her death was announced in a message on her official X account, which thanked supporters for their prayers.
  • West joined the Naval Surface Warfare Center Dahlgren Division in 1956 and served for more than four decades before retiring in 1998.
  • During the 1970s and 1980s she developed highly precise mathematical models of Earth’s shape using satellite data.
  • Those models formed a technical foundation for what became the Global Positioning System.
  • Public recognition of her contributions grew late in life, including a 2018 induction into the U.S. Air Force Space and Missile Pioneers Hall of Fame, as GPS spread from military origins to widespread civilian use.
