“The authors do the impossible, making an intricate technological advance fascinating to read. They offer an informative and well researched account of how GPS proved its worth even before the system was complete. The results it provided in the Persian Gulf War were truly revolutionary. With this seemingly miraculous kick-off, GPS technology was almost immediately integrated throughout military systems. Entrepreneurs immediately picked up on this, and made it equally successful in commerce.”
—Walter J. Boyne, author of How the Helicopter Changed Modern Warfare and former director of the National Air and Space Museum of the Smithsonian Institution
