			        		&quot;A practical, convenient, and economical solution for the mariner who wants a backup system to GPS that contains all the essential instructions and data.&quot;&#x2014;Foundation for the Art of Navigation Your All-in-One Navigation Tool Kit Celestial navigation remains an essential skill for every mariner who ventures out of sight of land. In this era of electronic navigation, it is the perfect backup system, enabling you to determine your position when the GPS malfunctions or your boat loses electrical power. Here in one volume is every bit of information you need to understand the process, take sights, and find your location anywhere in the world. Compiled for beginning and experienced celestial navigators alike, and elegantly designed on the assumption that 1-mile precision is perfectly adequate for backup navigation, this handy volume replaces $300 worth and thousands of pages of guides, tables, and almanacs. The Complete On-Board Celestial Navigator includes:  A clear, concise primer/refresher that explains the entire process A five-year nautical almanac (2007&#x2013;2011) for determining precise star, sun, moon, and planet locations at the time of sighting A star finder Sight reduction tables for crunching the numbers and producing a fix anywhere in the world  &quot;The only complete self-contained work available. When your electronic navigation fails, &apos;steering by the stars&apos; will guide you safely to your destination.&quot;&#x2014;Sydney Afloat (Australia) George G. Bennett, Ph.D., is the owner and director of CN Systems, which produces navigational calculator and computer software. He is the former head of the School of Surveying, Faculty of Engineering, at the University of New South Wales. An elected Fellow of the Institution of Surveyors and the Institute of Navigation, he has served as a visiting scientist at Her Majesty&apos;s Nautical Almanac Office at the Royal Observatory.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Interesting and surprisingly complete reference!
            
*by A***H on November 13, 2009*

I had the prior version of this book and loved it.  However, the tables that are included are only good for about 4 years and my old one was about 2 years out of date.  I loved my previous one and used it a lot as I practice to stay "current" relative to celestial navigation.  I find that this reference and its self-contained approach is very accessible, easy to use and is surprisingly accurate.  I'm glad I'm keeping up with the "current" versions.The service was excellent.
  

### ⭐⭐⭐⭐⭐ celestial navagation
            
*by M***L on October 12, 2010*

I purchased this book as a gift. The recipient was very excited and said that this is an informative easy read.
  

### ⭐⭐⭐⭐ A great practical tool
            
*by J***K on January 18, 2011*

I used this book when I was the navigator on board a boat in the 2007 Transpac race, which goes from Long Beach, California to Oaha, Hawaii, and I'll be using it again for the 2011 Transpac.  Of course, all boats in these races are using GPS and satellite weather and laptops, but the rules of the race require each navigator to take 4 celestial sights and plot 4 lines of position, presumably as a nod to both safety and sailing history.I'm a child of the GPS era as far as navigating goes, and I had zero knowledge of celestial navigation going into my 2007 race.  The advantage of this book is that it has everything you need -- celestial almanac, sight reduction tables, calculation sheets, plotting sheets, and a simple system that ties these components together, all in one compact form.  The hardest arithmetic required is addition, and the plotting skills amount to measuring distance on a scale with a pair of calipers, and drawing lines with a straightedge.There are some minor disadvantages.  First, to keep the book compact, the accuracy of the celestial almanac has been reduced by a factor of ten.  That may sound bad, but in practice, with a crummy sextant and feeble skills, I was able to compute a celestial position within 5 miles of the reported GPS position.  It's extremely hard for me to imagine a real-life emergency where I'd need better than that.Second, if you've already learned the standard method for converting celestial sights to lines of position, you can't use it here.  In order to get such a compact book, Bennett has done some extremely clever things, but you have to follow his specific algorithm.  The book is pretty terse, and sometimes it can be frustrating trying to understand what he wants you to do.  It took me forever to understand his explanation of Weir diagrams, after which I realized I didn't need them anyway.If you want to learn the principles of celestial navigation, this book isn't the place to start.  But for a practical tool that's compact, easy to use once you understand it, and that will get you home when a rogue wave has smashed through your cockpit door and fried all your electronics, you cannot do better than this.
