Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Practical Guide to Celestial Navigation written by Phil Somerville and published by Bloomsbury Publishing. This book was released on 2021-10-14 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The practical guide to celestial navigation - know what to do step by step, understand why you're doing it, and be confident that you can put it into practice when on board. Did you know that a person standing on the equator is effectively travelling at 900mph? And did you know that you can use this information to work out where you are in the world, to an accuracy of about 3 or 4 miles? No GPS, no computers. Just a sextant, some tables from an Almanac and the knowledge in this book. It's the only back up if the GPS goes down, so it's a matter of safety. If you want to qualify as a commercial skipper/superyacht captain you need to know how to carry out celestial navigation. And if you want to pass the RYA Ocean YachtmasterTM exam, you need to know it too. It's a major stumbling block for many sailors wanting or needing to take their next qualifications, and the other books on the market are complex and often assume some prior understanding. This book fulfils the need for a clear explanation of celestial navigation, illustrated with colour diagrams and including unique checklist sheets to enable you to repeat all those calculations you learned back at home, when you're on deck. Without overwhelming the reader with a load of theory from the off, the author breaks down what you need to do, step by step, explaining why at every point – giving the information context, and making it more interesting and memorable. He has trained students in this subject for years, and here he's able to use his experiences of what works, and what are the common pitfalls – he even includes a troubleshooting chapter near the end, going through errors commonly made, and how to spot them. The objective is that readers will finish the book not only knowing what to do, but really understanding why, and being able to make sense of it all again later (rather than just getting through and exam and finding themselves at a loss when on deck). The author also includes time-tested 'proformas' – quick reference sheets that sailors can refer to when they come to putting the theory into practice on board, avoiding the terrifying 'cold start' that most sailors experience when they suddenly need to put their theoretical knowledge to the test in the real world.

Book excerpt: 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.

Download or read book The Lost Art of Finding Our Way written by John Edward Huth and published by Harvard University Press. This book was released on 2013-05-15 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long before GPS, Google Earth, and global transit, humans traveled vast distances using only environmental clues and simple instruments. John Huth asks what is lost when modern technology substitutes for our innate capacity to find our way. Encyclopedic in breadth, weaving together astronomy, meteorology, oceanography, and ethnography, The Lost Art of Finding Our Way puts us in the shoes, ships, and sleds of early navigators for whom paying close attention to the environment around them was, quite literally, a matter of life and death. Haunted by the fate of two young kayakers lost in a fog bank off Nantucket, Huth shows us how to navigate using natural phenomena—the way the Vikings used the sunstone to detect polarization of sunlight, and Arab traders learned to sail into the wind, and Pacific Islanders used underwater lightning and “read” waves to guide their explorations. Huth reminds us that we are all navigators capable of learning techniques ranging from the simplest to the most sophisticated skills of direction-finding. Even today, careful observation of the sun and moon, tides and ocean currents, weather and atmospheric effects can be all we need to find our way. Lavishly illustrated with nearly 200 specially prepared drawings, Huth’s compelling account of the cultures of navigation will engross readers in a narrative that is part scientific treatise, part personal travelogue, and part vivid re-creation of navigational history. Seeing through the eyes of past voyagers, we bring our own world into sharper view.
Download or read book Navigation A Very Short Introduction written by Jim Bennett and published by Oxford University Press. This book was released on 2017-02-10 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Bronze Age mariners of the Mediterranean to contemporary sailors using satellite-based technologies, the history of navigation at sea, the art of finding a position and setting a course, is fascinating. The scientific and technological developments that have enabled accurate measurements of position were central to exploration, trade, and the opening up of new continents, and the resulting journeys taken under their influence have had a profound influence on world history. In this Very Short Introduction Jim Bennett looks at the history of navigation, starting with the distinctive cultures of navigation that are defined geographically - the Mediterranean Sea, and the Pacific, Indian, and Atlantic Oceans. He shows how the adoption of mathematical methods, the use of instruments, the writing of textbooks and the publication of charts all combined to create a more standardised practice. Methods such as longitude-finding by chronometer and lunar distance were complemented by the routine business of recording courses and reckoning position 'by account'. Bennett also introduces the incredible array of instruments relied on by sailors, from astrolabes, sextants, and chronometers, to our more modern radio receivers, electronic equipment, and charts, and highlights the crucial role played by the individual qualities of endeavour and resourcefulness from mathematicians, scientists, and seamen in finding their way at sea. The story of navigation combines the societal, the technical, and the human, and it was vital for shaping the modern world. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly.

Download or read book Golden Thread of Time written by Crichton E.M Miller and published by eBook Partnership. This book was released on 2014-04-10 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time is the most important commodity on Earth, we live by it and we die by it, it gives order to our lives and we control all of our modern society using time and its modern instruments. We think we have mastered time, what if we are wrong?We are told in the Bible in Genesis 1 verse 14, that our ancestors measured time by the stars and moon and we are told by evolutionists that ancient people used basic astronomy to achieve a crude understanding of time.What if the war between science and religion has psychologically obscured an obvious and indisputable fact from us all?If our ancestors could measure time accurately, then all our science and technical achievements would have been inherited in a tree of knowledge that brought us to where we are today.What if the Church in its desperate struggle to keep a profitable business alive and functioning has created such division over the ages that we do not understand the simple messages left by our ancestors on the real nature of time.What if both church and crown in their pact to rule Europe, obscured a scientific system inherited from Palaeolithic and Neolithic sea faring hunter gatherers that was used for thousands of years to keep time while measuring and travelling the planet and developing a philosophy that maintained a balance with Nature?There is a golden thread of truth running through our history that millions cannot see, but that if we did, it may give us hope for our children in a world adrift without an anchor, where time runs faster, exploitation is rife and honesty is a bye word from a lost time, imagined to be better, where society cared about its people and families about their children living by rules that were easy to understand and no one old, poor or disabled lived in isolation.The Golden Thread of Time is designed to give hope where it does not exist, providing answers where there have been none while motivating people to look beyond the mundane toward the light.Do you care?
Download or read book Navigating the C 124 Globemaster written by Billy D. Higgins and published by McFarland. This book was released on 2019-07-25 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The C-124 Globemaster--a U.S. military heavy-lift transport in service 1950 through 1974--barreling down a runway was an awesome sight. The aircraft's four 3800 hp piston engines (the largest ever mass-produced), mounted on its 174-foot wingspan, could carry a 69,000-pound payload of tanks, artillery or other cargo, or 200 fully equipped troops, at more than 300 mph. The flight crew, perched three stories above the landing gears in an unpressurized cockpit, relied, like Magellan, on celestial fixes to navigate over oceans. With a world-wide mission delivering troops and materials to such destinations as the Congo, Vietnam, Thule, Greenland and Antarctica, the Globemaster lived up to its name and was foundational to what Time magazine publisher Henry Luce termed the "American Century." Drawing on archives, Air Force bases, libraries and accident sites, and his own recollections as a navigator, the author details Cold War confrontations and consequent strategies that emerged after Douglas Aircraft Company delivered the first C-124A to the Military Air Transport Service in 1949.
Download or read book Wayfinding written by M. R. O'Connor and published by St. Martin's Press. This book was released on 2019-04-30 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: At once far flung and intimate, a fascinating look at how finding our way make us human. "A marvel of storytelling." —Kirkus (Starred Review) In this compelling narrative, O'Connor seeks out neuroscientists, anthropologists and master navigators to understand how navigation ultimately gave us our humanity. Biologists have been trying to solve the mystery of how organisms have the ability to migrate and orient with such precision—especially since our own adventurous ancestors spread across the world without maps or instruments. O'Connor goes to the Arctic, the Australian bush and the South Pacific to talk to masters of their environment who seek to preserve their traditions at a time when anyone can use a GPS to navigate. O’Connor explores the neurological basis of spatial orientation within the hippocampus. Without it, people inhabit a dream state, becoming amnesiacs incapable of finding their way, recalling the past, or imagining the future. Studies have shown that the more we exercise our cognitive mapping skills, the greater the grey matter and health of our hippocampus. O'Connor talks to scientists studying how atrophy in the hippocampus is associated with afflictions such as impaired memory, dementia, Alzheimer’s Disease, depression and PTSD. Wayfinding is a captivating book that charts how our species' profound capacity for exploration, memory and storytelling results in topophilia, the love of place. "O'Connor talked to just the right people in just the right places, and her narrative is a marvel of storytelling on its own merits, erudite but lightly worn. There are many reasons why people should make efforts to improve their geographical literacy, and O'Connor hits on many in this excellent book—devouring it makes for a good start." —Kirkus Reviews
Download or read book Celestial Navigation written by David Burch and published by . This book was released on 2016-03-04 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been used for 30 years, updated periodically as needed. More than 20,000 students have successfully learned ocean navigation from these materials and gone on to cross oceans or circumnavigate the globe. This book covers how to find position at sea from timed sextant sights of the sun, moon, stars, and planets plus other routine and special procedures of safe, efficient offshore navigation. No previous navigation experience is required. The only math involved is arithmetic (adding and subtracting angles and times). This is a practical, how-to-do-it book, which also includes clear explanations of how it works and how to do it well. Plus this book includes other crucial factors of ocean navigation besides just finding out where you are from the stars, such as logbook procedures, dead reckoning, error analysis, route planning, and more. At the end of this book, you will be ready for ocean navigation. The book includes: text, practice problems, tables selections, detailed glossary, and full solutions. Printable work forms, plotting sheets, and other resources are available at no charge from www.starpath.com/celnavbook. Preface to the Second Edition: We are pleased to say that after ten more years of using this text we do not find reason to change the basic approach and methods of the teaching. We still use most of the same examples, which are now quite old, but that is the beauty of celestial navigation. It has not changed, so we do not benefit in any way from making all new examples, which would bring with them more chance of error in a book of many numbers. We have, however, notably improved and expanded the book. Each section has been updated and reformatted for a clearer presentation, often in response to student questions over the years. New graphics have been added and older ones all updated. There is much new content in the text, especially in the In-Depth chapter, including more detailed discussion of the sailings and more background on the principles. New sections were added on general ocean navigation and optimizing the fixes. We have also updated the electronic navigation section, as most ocean navigators will also be using other tools besides celestial.
