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, the authors 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. Told by the son of a navy insider—whose work helped lay the foundations for the system—and a science and technology journalist, the story chronicles the research and technological advances required for the development of GPS. The authors peek behind the scenes at pivotal events in GPS history. They note how the technology moved from the laboratory to the battlefield to the dashboard and the smartphone, and they raise the specter of how this technology and its surrounding industry affect public policy. Insights into how the system works and how it fits into a long history of advances in navigation tie into discussions of the myriad applications for GPS.

Over the course of the twentieth century, there was a major shift in practices of mapping, as centuries-old methods of land surveying and print publication were incrementally displaced by electronic navigation systems. William Rankin argues that although this shift did not render traditional maps obsolete, it did revise the goals of the mapping sciences as a whole. Military cartographers and civilian agencies alike developed new techniques for tasks that exceeded the capabilities of paper, such as aiming long-range guns, navigating in featureless environments, regularizing air travel, or drilling for offshore oil. "After the Map "reveals the major conceptual ramifications of these and other changes and in doing so offers a new way of understanding the central political-geographic shift of the twentieth century. Seen first and foremost as affecting a transformation in the nature of "territory," the change from paper mapping to electronic systems is not a story about technological improvement or the wizardry of precision; instead, it is about the "kind" of geographic knowledge and therefore governance that can exist in the first place.
