Reseña del libro "GPS: The Machine That Knows Where Everything Is: How Satellite Navigation Was Built, How It Works, and Why Every Phone, Plane, and Bank on Earth ... Nobody Sees (MACHINES THAT RUN THE WORLD) (en Inglés)"

Your phone tells you exactly where you are without sending a single signal back—so what is it actually listening to? This is not a spy story or a physics textbook. It is an explain-the-machine book: a clear tour of the system quietly running under modern life. GPS is really a clock-sharing machine disguised as a map—every receiver on Earth finds its position by timing a radio signal to billionths of a second and multiplying by the speed of light. Get the time wrong, and the map goes wrong with it. Inside, you'll find: The five-and-a-half-hour morning in January 2016 when a software update shifted GPS time by thirteen microseconds—3.9 kilometers of error—knocking BBC digital radio off step. The Labor Day weekend in 1973 when officers in an empty Pentagon merged two rival Navy and Air Force programs into the design that still runs the world's satellite navigation. The 2019 study putting GPS's benefit to the American private sector at $1.4 trillion, and the cost of losing the signal at roughly $1 billion a day. The jamming out of the Baltic since 2022, which disrupted 123,000 flights between January and April 2025 alone—one aircraft every eighty-four seconds. The three rival systems built by nations unwilling to depend on someone else's satellites—Russia's GLONASS, Europe's Galileo, China's BeiDou, India's NavIC—the clearest measure of what a free signal is worth. No engineering degree required. This book is for anyone who has watched the blue dot on a map and never wondered how it finds itself among satellites it has never spoken to—office workers, students, and the merely curious. It is a machine nobody sees, everybody depends on, and almost no one can explain.
