    Hello Andrés and Others,

    Nice diagram ! Could be compared to the synoptics of Philippe Bourbon in his book, with hypotheses dispatched differently.

    "La Navigation astronomique: fondements, applications, perspectives" Institut Oceanographique 2000, IBSN 2-903581-24-X

    Many other methods are worth to be taken into account. Noticeably:

    - Cdt Paoli trigonometric method, which is fully analytics for n>=3 and integrates the vessel movement

    - Yvon-Villarceau who was the first to convert the observation data into linear equations (1877), waiting for matrix solution  

    - Georges Bodenez method, which pionieered the matrix approach on 1976-1977 (one century after Yvon-Villarceau!)

    - Van Katwijck method, which is between Kaplan and Metcalf methods (1981)


    (not to mention recent methods like Dozier, Kotlaric, Hounau, Gery...) 

    Regards, YRJ
