If you use GPS today, it's thanks to scientist Gladys West: she changed the way we orient ourselves
From geodesy (a complex of operations to connect points on the earth's surface) to the models of the earth's shape that today allow us to determine the position of any point on earth with a margin of error of only a few centimeters, Gladys West played an important role in the development of today's global positioning system, better known as the GPS.
