He is best known as the lead architect, advocate and developer, with early contributions from Ivan Getting and Roger Easton, of the Air Force NAVSTAR program, better known as Global Positioning System. He was also the co-principal investigator (co-PI) and program manager on Gravity Probe B, which tested gravitomagnetism and was the first direct mechanical test of Einstein’s General Relativity. He has received numerous awards and honors for GPS and contributions to engineering and invention, including the Charles Stark Draper Prize, National Inventors Hall of Fame, and IEEE Medal of Honor, among others. In 2019, Bradford Parkinson shared the Queen Elizabeth Prize for Engineering with three other GPS pioneers (James Spilker, Hugo Freuhauf, and Richard Schwartz). Education For his secondary education, Parkinson attended the Breck School, then a small, all-boys preparatory school, graduating in 1952. Parkinson has credited his experiences at the Breck School for inspiring in him an early love of math and science, an interest which eventually became his life's calling. Parkinson was a distinguished graduate of the United States Naval Academy, graduating in 1957
