What’s new: The passing of an important contributor to GPS and all the benefits we receive from space-based PNT.
Why it’s important: It is important to recognize those who are deserving but not well recognized in the popular conception.
What else to know: We lived in southern Virginia in the 50’s. Her getting hired at Dahlgren in 1956, was an impressive achievement in and of itself.

Mathematician Gladys West dies at 95. She was a hidden figure behind GPS.
Without the mathematical model that she helped refine, “the extraordinary positioning, navigation, and timing accuracy of GPS would be impossible to achieve.”
Dr. West, who died Jan. 17 at 95, used her mathematical skills to become a barrier-breaking researcher for the Navy, mastering a bulky supercomputer known as Stretch while calculating satellite orbits and developing a precise model of the Earth’s surface. Her research laid the groundwork for the Global Positioning System, GPS, a technology that has made getting lost a thing of the past. Thanks in part to Dr. West, anyone with a smartphone — or a receiver-equipped car, airplane or boat — can navigate easily from one place to the next, without having to stop to ask for directions.
