   The next time you use any navigation device, software or Google Maps thank Dr. Gladys West. Her contributions to the mathematical modeling of the shape of Earth, and her work on the development of the satellite models that were eventually incorporated into  the Global Positioning System (GPS) technology. #BlackMastodon #BlackHistoryMonth
