Arithmetic led Gladys West from the Virginia farm of her childhood 100 miles north to a United States naval facility, the place she did sophisticated calculations and programmed computers for four many years until eventually her retirement in 1998. She led teams on groundbreaking satellite tasks checking the world’s oceans and generating a specific model of Earth’s surface area, a department of science referred to as geodesy (gee-ODD-es-see). Her work turned the foundation for the World-wide Positioning Program (GPS). Satellite-centered mapping units are applied around the world, but not by West. She prefers paper maps.
