When I first learned celestial navigation I found it surprising that there are no free versions of the Nautical almanac to be found on the internet. Although I am not a very good programmer I decided to correct this problem. The results are the PDF files that can be downloaded here. I compared the results to the 2009 version of the official Nautical Almanac and found no differences larger than 0.3´. Which is good enough for me. I believe that the algorithm is sound but cannot guarantee the absence of larger errors. Anyone who needs the Nautical Almanac for security relevant applications should buy the official one. My Tables should be fine for anyone wanting to learn the fine art of navigating by the stars.
Have fun and always fair winds.
Tables in PDF format
Full nautical almanac with all the variable tables:
For those that only want to do sun sights I compiled tables just for the sun. These tables are very compact and one or two sheets should be sufficient for most passages:
One will also need the static tables corresponding to the „increments & corrections part in the nautical almanac. Mine have a slightly different format but should be easy enough to use.:
And plotting sheets in different formats:
All these tables were created by a small Python program. Most of the heavy computing is done by the free Pyephem libraries. Typesetting is done by TeX/LaTeX So before you can use this program you need to install:
Last but not least you need to download the python script which I release under the GPLv2.
