    Astronavigation and the 21st century
    From: Andr�s Ruiz

    I do not agree with everything said in this article:
    ASTRONOMICAL NAVIGATION AT THE BEGINNING OF THE THIRD MILLENNIUM 
    Stajic, D. [p. 209-216, PDF, 89KB]
    http://www.aob.bg.ac.yu/paob/75/pdf/209-216.pdf
    
    For yachts in Spain, (of course for merchants), and France the sextant is 
    mandatory aboard for oceanic navigation.
    UK, USA, other countries?
    
    The linked file is: "Automated Celestial Systems for Attitude & Position 
    Determination" by George Kaplan, USNO,
    notes the use of celestial navigation in defense, (DoD) by means of a Star Tracker.
