Link: Gladys West made GPS possible

Mother of GPS, Gladys West, Finally Gets Proper Recognition by Judith Fogel. Did you know GPS was made possible by a Black woman (who is still alive)? I sure didn't!

Gladys West and her husband Ira were both mathematicians at Dahlgren Naval Base, then called Dahlgren Naval Proving Ground. West was hired in 1956. Her extraordinary contributions to the geodetic modeling of the earth became the foundation for the Global Positioning System (GPS). But few knew how much this Black woman changed the way we navigate.
