    Yes, I wish. I wish the stars to be called CelNav.
    Waves and sargassos I don't with to be called Cel nav.

    I agree. One can do DR without a compass, using the stars.

    Thanks.
    
    >So better precision...
    
    No. I claim (based on what I know)
    that there was NO way to determine
    longitude,
    with ANY precision,
    Even with 180d precision (that is to determine, in which hemisphere
    you are) unless you use "Western methods", pioneered by
    Alexandria Greeks in III cent BC based on the Moon.
    
    Then forgotten for 1500 years at least (according to Herbert Prinz)
    And then revived in XVIII century. By Westren Culture.
    
    Alex.
