The Nautical Almanacs and Sun Almanacs listed on our site were created or derived from a program written by the great Norwegian sailor Enno Rodegerdts. Without his work this site wouldn't exist. |

great work of Dr. Rodegerdts and refined it to the
excellence you see on our site. He is unique
in this present age of ambition and represents a man
of generosity, humility and familiarity of knowledge
in making simple those things which are wise. Knowledge,
long and painstaking hours has he expended in
developing the works present. And for
what? Obscurity? I say, nah, but

practice celestial navigation. He has offered
his programs at no charge on his site so that you
