In Pinpoint, Greg Milner takes us on a fascinating tour of a hidden system that touches almost every aspect of our modern life. It is as ubiquitous and essential as another Cold War technology, the Internet. Even as it guides us across town, GPS helps land planes, route mobile calls, anticipate earthquakes, predict weather, locate oil deposits, measure neutrinos, grow our food, and regulate global finance. Over the last fifty years, humanity has developed an extraordinary shared utility: the Global Positioning System. Pinpoint tells the story of GPS, a scientific marvel that enables almost all modern technology-but is changing us in profound ways.
