    Celestrial Navigation
    From: Vic Fraenckel
    Date: 2002 Jun 30, 18:26 -0400

    I joined this Mail List back in March. I have not received any mail from the
    list in the past month or two. Is anyone out there any more?
    I have wanted to do tableless celestrial navigation on my computer for quite
    some time and have been searching for a way to do this. My trusty Google
    engine finally hauled me to Paul J. Heafner's "Funamental Ephemeris
    Computations" and the "JPL Planetary and Lunar Ephemerides" CDROM. I have
    been studying the book to try and get an understanding of what's going on in
    there. In the past couple of months I have progressed about 1/3 of the way
    thru the book and have tried out many of the routines found there. Now that
    I have invested a goodly amount of time in this project I have come to the
    point of wondering if I am barking up the wrong tree. The focus of the book
    is Astronomy. As I am coming into this as a beginner as far as the Astronomy
    is concerned, I would like to know or understand that this research is going
    to provide me with what my goal is - tableless celestrial navigation.
    Programming is NO mystery to me as a retired Software Engineer. I am
    assuming that given the understanding of extracting data from the JPL
    Ephemerides and massaging it with software will yield me the figures that
    are equilvalent to those that we all can find in the Nautical Almanac and
    that I will end up with the proper algorithms to go from sextant to a
    position that is reliable.
    ANY enlightenment would be greatly appreciated.
