Book Description
Sailors have been navigating the seas for thousands of years, and navigational technology has progressed exponentially during that time. This concise yet comprehensive volume begins with the impressive developments in navigation made by early navigators and follows the art and science of navigation through the ages to their culmination in the huge advances made by our contemporaries. With a focus on the navigational tools invented by each age and civilization, Launer traces the evolution of humankind¿s navigational skills from the Kamal of the Arabs and the Lead-line first used by the Romans to the radio and satellite communication devices available to modern sailors. He pays homage to the Polynesians who, in the absence of a written language were able to pass down their navigational skills through generations, and to the adventurous Vikings, who managed to find their way from Scandinavia to England, Iceland, Greenland and beyond; but he also covers the practical applications of the complex technologies found on most boats today, such as GPS. Generous illustrations help readers envision the tools in use. Navigation Through the Ages will appeal to sailors and lay readers alike¿anyone with an interest in the history of science and the exploration of our world.

Book Description
Many books on celestial navigation take shortcuts in explaining concepts; incorrect diagrams and discussion are often used for the sake of moving the student along quickly. This book tells the true story-and the whole story. It conveys celestial navigation concepts clearly and in the shortest possible time.It's tailored for navigation in the GPS age-a time of computers, calculators, and web resources. Although it covers all of the traditional methods of 'working a sight, ' the primary thrust is using the (under $10) scientific calculator. By using equations that you key into your calculator, this book guides you toward a better understanding of the concepts of celestial navigation.You will learn novel ways to plot lines of position, ways to check your sextant accurately by star sights, and how to tell what time it is from a moon sight. The many appendices are a treasure of references and explanations of abstract ideas. Celestial Navigation is a crucial skill for the offshore navigator to know, this book provides the shortest path to that knowledge.

Book Description
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.

Book Description
A FASCINATING INVESTIGATION OF HOW WE NAVIGATE THE PHYSICAL WORLD, INNER NAVIGATION IS A LIVELY, ENGAGING ACCOUNT OF SUBCONSCIOUS MAPMAKING. Why are we so often disoriented when we come up from the subway? Do we really walk in circles when we lose our bearings in the wilderness? How -- and why -- do we get lost at all? In this surprising, stimulating book, Erik Jonsson, a Swedish-born engineer who has spent a lifetime exploring navigation over every terrain, from the crowded cities of Europe to the emptiness of the desert, gives readers extraordinary new insights into the human way-finding system. Written for the nonscientist, Inner Navigation explains the astonishing array of physical and psychological cues the brain uses to situate us in space and build its "cognitive maps" -- the subconscious maps it employs to organize landmarks. Humans, Jonsson explains, also possess an intuitive direction frame -- an internal compass -- that keeps these maps oriented (when it functions properly) and a dead-reckoning system that constantly updates our location on the map as we move through the world. Even the most cynical city-dweller will be amazed to learn how much of this innate sense we use every day as we travel across town or around the world. Both a scientific and a human story, Inner Navigation contains a rich assortment of real-life insights and examples of the navigational challenges we all face, no matter where or how we live. It's a book that is as provocative to ponder as it is delightful to lose yourself in. Don't worry: Erik Jonsson will help you find your bearings.

Book Description
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.

Book Description
Today travellers by land, sea and air take accurate navigation for granted but it was not always thus. The author, a highly experienced sailor, sets out to record the development of navigational techniques from the earliest time, five millenniums ago. As explorers started to venture offshore into the unknown they had to rely on the sun and stars for direction. From this pioneers turned to mathematics, astrolobes, sextants and increasing accurate clocks to measure latitude and later longitude. More recently major breakthroughs with electronic navigation, GPS and other satellite systems have revolutionised travel. Focusing primarily but not exclusively on marine navigation, the author weaves a fascinating course through the successes and failures of mankind’s quest to explore his world. The result is a thoroughly entertaining and informative work which has no rival.
