A pioneer of GPS passes away | Scientific American

James Spilker Jr., a pioneer of groundbreaking technology that profoundly changed the world, has passed away. Spilker, along with colleagues Brad Parkinson, Hugo Fruehauf and Richard Swartz are the master minds behind GPS. Together the four of them were to receive the Queen Elizabeth Prize for Engineering, the most prestigious engineering award in the world on December 3, 2019 at Buckingham Palace. Unfortunately Spilker passed away before the formal ceremony. His wife, Anna Maire Spilker, will complete the journey without him. James Spilker was an expert on signal-timing technology. He designed and implemented the payload for the world’s first military satellite communications system while working at Ford Aerospace. His company, Standford Telecommunications, recommended the GPS structure for code division multiple access (CDMA). This signal is what makes consumer GPS technology possible today.
