    Hi Hewitt,
     
    Thanks for taking the time to do this via the table method.  I have to say that I am pretty disappointed with the longitude determination from this method.  4.3' is a pretty big error in my book and would send me looking for math or sight errors if it happened out here.  I find it curious why there is such a difference between this method and the ones Peter and I used to get much more accurate fixes.
     
    Being unfamiliar with the book that you used, I am wondering if there is some explanation as to why the results differ so greatly.

    Hi Jeremy -

    Here's a paper-and-paper method of finding Longitude at Noon based on
    the motion correction table published in Latitude and Longitude by the
    Noon Sight.

    My work sheet is the .doc attachment.
    The table scan is the .jpg attachment.

    As you'll see, this method differs from your 1300 GPS by .4' in Lat
    and 4.3' in Lon.

    Thanks for providing data from actual combat conditions. :-)

    Hewitt
