The Fascinating History of GPS: How a Cold War Invention Changed the Way We Navigate the World by Revin Laxtor is a captivating exploration of one of humanity’s most transformative achievements—the Global Positioning System. In an age where a simple blue dot on a smartphone can guide us effortlessly across continents, it’s easy to forget how recently this technology was born and how profoundly it has reshaped our world. This book takes readers on a remarkable journey through time, science, and ingenuity, revealing how a Cold War innovation became the invisible force powering modern life.

At its heart, this is the story of how humankind learned to answer one of the oldest and most essential questions: Where am I? From the early days of sailors steering by the stars and explorers navigating by compass and sextant, to the dawn of satellite tracking and the creation of a global navigation system, Revin Laxtor traces every step of our quest for precision. Each chapter brings history to life—from the first beeps of Sputnik echoing across the sky, to the secret military experiments that would evolve into NAVSTAR GPS, to the moment the system opened to the world and forever changed how we move, communicate, and connect.

The Fascinating History of GPS begins with humanity’s ancient struggle to navigate—the art and science of reading the heavens and the Earth. It then delves into the pivotal moment in 1957 when the Soviet Union launched Sputnik, a single metal sphere that unknowingly gave birth to satellite-based navigation. The book explains how American scientists discovered the Doppler effect’s potential for tracking movement from space, leading to the U.S. Navy’s pioneering Transit system—the first step toward a world guided by signals from above.
