    Re: CelNav without sextant

    Here is a Cel Nav method even without radio:-)
    I only assume we have a reasonable watch (available
    at Wall Mart) and an almanac. And that the Moon
    is available and moves in  the "correct direction" :-)
    
    That's all. And a clear sky.
    
    You time the sunset using your watch.
    Then you time an occultation to check your watch
    against GMT.
    And then you time the sunrise using the same watch.
    
    Potential problems:
    1. How precisely you can time a sunrise/sunset?
    (The problem is refraction. The alt. is "zero",
    or more precisely, something like 15')
    2. To use the occultation you need the approx.
    altitude of the moon at this moment, (because
    of the parallax, and less importantly, refraction),
    so you need your DR
    place.
    
    Alex.
