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.
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. Told by a 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. Easton and Frazier note how the technology moved from the laboratory and 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. Purchase the audio edition.
Discover the definitive history of DARPA, the Defense Advanced Research Project Agency, in this Pulitzer Prize finalist from the author of the New York Times bestseller Area 51. No one has ever written the history of the Defense Department's most secret, most powerful, and most controversial military science R&D agency. In the first-ever history about the organization, New York Times bestselling author Annie Jacobsen draws on inside sources, exclusive interviews, private documents, and declassified memos to paint a picture of DARPA, or "the Pentagon's brain," from its Cold War inception in 1958 to the present. This is the book on DARPA -- a compelling narrative about this clandestine intersection of science and the American military and the often frightening results.
"The Guide to GPS Positioning is a self-contained introduction to the Global Positioning System, designed to be used in any of the following three ways: as a self-study guide, as lecture notes for formal post-secondary education courses, or as hand-out material to support short-course and seminar presentations on GPS." -- Introduction.
If you want to know where you are, you need a good clock. The surprising connection between time and placeais explored inaTime and Navigation- The Untold Story of Getting from Here to There, the companion book to the National Air and Space Museum exhibition of the same name. Today we use smartphones and GPS, but navigating has not always been so easy. The oldest "clock" is Earth itself, and the oldest means of keeping time came from observing changes in the sky. Early mariners like the Vikings accomplished amazing feats of navigation without using clocks at all. Pioneering seafarers in the Age of Exploration used dead reckoning and celestial navigation; later innovations such as sextants and marine chronometers honed these techniques by measuring latitude and longitude. When explorers turned their sights to the skies, they built on what had been learned at sea. For example, Charles Lindbergh used a bubble sextant on his record-breaking flights. World War II led to the development of new flight technologies, notably radio navigation, since celestial navigation was not suited for all-weather military operations. These forms of navigation were extended and enhanced when explorers began guiding spacecraft into space and across the solar system. Astronauts combined celestial navigation technology with radio transmissions. The development of the atomic clock revolutionized space flight because it could measure billionths of a second, thereby allowing mission teams to navigate more accurately. Scientists and engineers applied these technologies to navigation on earth to develop space-based time and navigation services such as GPS that is used every day by people from all walks of life. While the history of navigation is one of constant change and innovation, it is also one of remarkable continuity. Time and Navigation tells the story of navigation to help us understand where we have been and how we got there so that we can understand where we are going.
For most of the twentieth century, maps were indispensable. They were how governments understood, managed, and defended their territory, and during the two world wars they were produced by the hundreds of millions. Cartographers and journalists predicted the dawning of a “map-minded age,” where increasingly state-of-the-art maps would become everyday tools. By the century’s end, however, there had been decisive shift in mapping practices, as the dominant methods of land surveying and print publication were increasingly displaced by electronic navigation systems. In After the Map, William Rankin argues that although this shift did not render traditional maps obsolete, it did radically change our experience of geographic knowledge, from the God’s-eye view of the map to the embedded subjectivity of GPS. Likewise, older concerns with geographic truth and objectivity have been upstaged by a new emphasis on simplicity, reliability, and convenience. After the Map shows how this change in geographic perspective is ultimately a transformation of the nature of territory, both social and political.
The definitive history of the Defense Advanced Research Projects Agency, the Pentagon agency that has quietly shaped war and technology for nearly sixty years. Founded in 1958 in response to the launch of Sputnik, the agency’s original mission was to create “the unimagined weapons of the future.” Over the decades, DARPA has been responsible for countless inventions and technologies that extend well beyond military technology. Sharon Weinberger gives us a riveting account of DARPA’s successes and failures, its remarkable innovations, and its wild-eyed schemes. We see how the threat of nuclear Armageddon sparked investment in computer networking, leading to the Internet, as well as to a proposal to power a missile-destroying particle beam by draining the Great Lakes. We learn how DARPA was responsible during the Vietnam War for both Agent Orange and the development of the world’s first armed drones, and how after 9/11 the agency sparked a national controversy over surveillance with its data-mining research. And we see how DARPA’s success with self-driving cars was followed by disappointing contributions to the Afghanistan and Iraq wars. Weinberger has interviewed more than one hundred former Pentagon officials and scientists involved in DARPA’s projects—many of whom have never spoken publicly about their work with the agency—and pored over countless declassified records from archives around the country, documents obtained under the Freedom of Information Act, and exclusive materials provided by sources. The Imagineers of War is a compelling and groundbreaking history in which science, technology, and politics collide.
