    GPS and Great Circle
    From: Joe Winlock
    Date: 2002 Oct 8, 09:41 -0700

    I am a lurker in this group and actually know only a smidge celestial
    navigation. I hope my question is not out of place here. I am curious
    whether my GPS follows the great circle route or Mercator rumb line when
    plotting long distance courses?
    Thanks for patience with the dummy,
    Joe...
