Global Positioning System—GPS. During the 1950s, Getting advanced the concept of using a system of satellites to allow the calculation of precise positioning data for rapidly moving vehicles. Parkinson created and ran the NAVSTAR GPS Joint Program Office from 1972–78. GPS is now routinely used for air traffic control systems, ships, trucks and cars, mechanized farming, search and rescue, tracking environmental changes, and more.
