Publisher's Synopsis
Over the last 50 years, humanity has developed an extraordinary global utility which is omnipresent, universal, and available to all. Neither the Internet nor the cloud would work without the Global Positioning System (GPS), a network of 30 satellites and their monitoring stations on Earth, which makes everything from the smartphone in your pocket to the precision planting of crops, to the Mars rover possible. 'Pinpoint' tells the remarkable story of GPS, from its conceptual origins as a bomb guidance system and its classified status to its present ubiquity and one of the most imporant technologies in the world.
