He is best known for designing the US Navy's Timation (time navigation) geopositioning system, which used multiple satellites carrying stable and ultra-precise clocks to send signals allowing earth-based receiving devices to calculate their exact locations. Patented in 1974 after several years of design, construction, and collaboration, Easton's system forms the foundation for the NAVSTAR-Global Positioning System (GPS).
