“GPS Declassified is a carefully researched, well-written, fast-paced, and thoroughly enjoyable book.”
—William F. Mellberg, Space Review

“As an introduction to GPS, its history, uses, issues and concerns, GPS Declassified can’t be beat.”
—Robert Schaefer, New York Journal of Books

“A fine and entertaining story of the origins of the Global Positioning System, a consequential space-age technology that has affected the lives of hundreds of millions in war and peace. Non-specialist readers will easily understand principles of this sophisticated system and appreciate difficulties of GPS development by visionary individuals.”
—Mike Gruntman, professor of astronautics at the University of Southern California at Los Angeles and author of Blazing the Trail: The Early History of Spacecraft and Rocketry

GPS Declassified examines the development of GPS from its secret, Cold War military roots to its emergence as a worldwide consumer industry. Drawing on previously unexplored documents, Richard D. Easton and Eric F. Frazier examine how military rivalries influenced the creation of GPS and shaped public perceptions about its origin. Since the United States’ first program to launch a satellite in the late 1950s, the nation has pursued dual paths into space—one military and secret, the other scientific and public. Among the many commercial spinoffs this approach has produced, GPS arguably boasts the greatest impact on our daily lives.

Richard D. Easton is the son of Roger L. Easton, the primary inventor of Timation, a satellite navigation system that became the basis of GPS. He divides his time between Dallas, Texas, and Williamsburg, Va.

Eric F. Frazier is an independent writer and editor based in Durham, NC.
