“At Dahlgren, West devoted herself to solving one of science’s most complex challenges: accurately modeling the shape of the Earth. Her painstaking calculations and programming helped transform raw satellite data into precise geodetic models, enabling reliable satellite-based navigation. That work ultimately became the backbone of the Global Positioning System (GPS) — now essential to aviation, shipping, emergency response, smartphones, and daily life worldwide.”
