    Datum for Nautical Almanac
    From: Michael Dorl
    Date: 2004 Oct 28, 08:48 -0500

    I've never seen it discussed here but it seems to me that sights reduced
    using Nautical Almanac data must be referenced to some datum. I checked my
    old NA (2000) and couldn't find any mention of what datum is used. Does the
    current NA have any statement about the reference datum?
    
    I would assume its WGS 84 (equivalent to NAD 83).
    
    Or maybe this is an unnecessary refinement for celestial navigation purposes?
