Download or read book GPS Declassified written by Richard D. Easton. This book was released on 2013. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.

Book Synopsis GPS by : Paul E. Ceruzzi

Download or read book GPS written by Paul E. Ceruzzi. This book was released on 2018-11-06. Available in PDF, EPUB and Kindle. Book excerpt: A concise history of GPS, from its military origins to its commercial applications and ubiquity in everyday life. GPS is ubiquitous in everyday life. GPS mapping is standard equipment in many new cars and geolocation services are embedded in smart phones. GPS makes Uber and Lyft possible; driverless cars won't be able to drive without it. In this volume in the MIT Press Essential Knowledge series, Paul Ceruzzi offers a concise history of GPS, explaining how a once-obscure space technology became an invisible piece of our infrastructure, as essential to modern life as electric power or clean water. GPS relays precise time and positioning information from orbiting satellites to receivers on the ground, at sea, and in the air. It operates worldwide, and its basic signals are free, although private companies can commodify the data provided. Ceruzzi recounts the origins of GPS and its predecessor technologies, including early aircraft navigation systems and satellites. He describes the invention of GPS as a space technology in the post-Apollo, pre-Space Shuttle years and its first military and commercial uses. Ceruzzi explains how the convergence of three major technological developments—the microprocessor, the Internet, and cellular telephony—enabled the development and application of GPS technology. Recognizing the importance of satellite positioning systems in a shifting geopolitical landscape—and perhaps doubting U.S. assurances of perpetual GPS availability—other countries are now building or have already developed their own systems, and Ceruzzi reports on these efforts in the European Union, Russia, India, China, and Japan.

Book Synopsis Time and Navigation by : Andrew K. Johnston

Download or read book Time and Navigation written by Andrew K. Johnston. This book was released on 2015-06-02. Available in PDF, EPUB and Kindle. Book excerpt: If you want to know where you are, you need a good clock. The surprising connection between time and place is explored in Time 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.

Book Synopsis After the Map by : William Rankin

Download or read book After the Map written by William Rankin. This book was released on 2016-07-01. Available in PDF, EPUB and Kindle. Book excerpt: 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.
