    Astronavigation by Lunar Distances
    From: Andrés Ruiz
    Date: 2010 Jul 16, 08:17 +0200

    A new release of Navigational Algorithms free software is available at my Website. CelestialFix includes Summner and Marcq solution, and more algorithms like Kaplan’s, Metcalf’s, and complex solution by Robin Stuart. Route Planner includes a GPX output for GC sailing.

     

    Also includes the new application Astronavigation by Lunar Distance that solves the following:

    • Nautical almanac: geocentric lunar distance and daily LD table
    • Time and position
    • Fix by two LD
    • Reduction of the observations to the same time

     

     

    For those unfamiliar with this method or for those who want to refresh their knowledge a very good starting point to learn this traditional method is the famous, in this list, About Lunars... available in PDF format, see “external links” in Wikipedia:
