    You can download the data files from the JPL solar system integration at:
    
    http://ssd.jpl.nasa.gov/horizons.html
    
    or you can get a much more compressed version (with claimed accuracy to
    better than an arcsecond) that also comes with programming hooks from a
    group of astrologers at:

    The latter is very easy to incorporate into your own almanac software.
