It also serves as a living link to centuries of explorers from centuries past. Beginning with the basics of positional astronomy, this guide moves on to the more complex math necessary to understand the ephemerides, tables showing the future positions of the stars and planets. These astronomical almanacs were the satellite navigation of their day. The objective of this book is twofold: to provide the reader with a concise, comprehensible manual on positional astronomy as it applies to astro-navigation and to furnish the concise algorithms for finding the position of the Sun and various navigational stars at any given instant. In a world where too many mariners and aeronauts rely solely on technology and are vulnerable to solar flares, electrical issues, and the like, this knowledge can be a life-saving backup, not to mention a fascinating study in its own rights. Included is an exact mathematical way to determine your position in the air or on the sea far more quickly and accurately than by using the old celestial navigational method, without even needing to know or understand the underlying mathematics. There is even a section that teaches how to measure the azimuth of a star using an analog wrist watch so if a sextant gets damaged, locating position is still possible. This book offers mathematicians and adventurers a way to determine position when the skies go dark. The U.S. Navy has recently realized that their electronic navigation systems are vulnerable to cyberattack, and as a result has instructed the Naval Academy to begin teaching celestial navigation again. 606 $aObservations, Astronomical 606 $aAstronomy?Observations 606 $aAerospace engineering 606 $aAstronautics 606 $aAstronomy 606 $aMathematical physics 606 $aAstronomy, Observations and Techniques$3https://scigraph.springernature.com/ontologies/product-market-codes/P22014 606 $aAerospace Technology and Astronautics$3https://scigraph.springernature.com/ontologies/product-market-codes/T17050 606 $aPopular Science in Astronomy$3https://scigraph.springernature.com/ontologies/product-market-codes/Q11009 606 $aMathematical Applications in the Physical Sciences$3https://scigraph.springernature.com/ontologies/product-market-codes/M13120 615 0$aObservations, Astronomical. 615 0$aAstronomy?Observations. 615 0$aAerospace engineering. 615 0$aAstronautics. 615 0$aAstronomy. 615 0$aMathematical physics. 615 14$aAstronomy, Observations and Techniques. 615 24$aAerospace Technology and Astronautics. 615 24$aPopular Science in Astronomy. 615 24$aMathematical Applications in the Physical Sciences. 676 $a520 700 $aZischka$b K.A$4aut$4http://id.loc.gov/vocabulary/relators/aut$01060059 906 $aBOOK 912 $a9910300538603321 996 $aAstronavigation$92510907 997 $aUNINA
