    Marco,

    The Van Allen method and paper mentioned earlier by Andrés is described at:
    https://www.ion.org/publications/abstract.cfm?articleID=100547
    Here is my brief summary:
    http://www.navigation-spreadsheets.com/lops.html
    and implementation that you can download:
    http://www.navigation-spreadsheets.com/uploads/lops.xls

    That said, another way to obtain the same answers is to use spherical trigonometry as described in John Karl’s book “Celestial Navigation in the GPS Age”, pp. 78-79”; you can download my implementation of those equations:
