    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:

    ·         In english http://en.wikipedia.org/wiki/Lunar_distance_(navigation)

    ·         In spanish http://es.wikipedia.org/wiki/Distancia_lunar

    What is NavList?

    NavList is a community devoted to the preservation and practice of celestial navigation and other methods of traditional position-finding. We're a group of navigators, navigation enthusiasts and hobbyists, mathematicians and physicists, and historians interested in all aspects of navigation but primarily those techniques which are non-electronic.

    To post a message, if you are already signed up as a NavList member, start a new discussion or reply to any posted message and use your posting code (this is a simple low-security password assigned when you join). You may also join by posting. Your first on-topic messsage automatically makes you a member, and a posting code will be assigned and emailed to you for future posts.

    Uniquely, the NavList message boards also permit full interaction entirely by email. You can optionally receive individual posts or daily digests by email, and any member can post messages by email (bypassing the web site) by sending to our posting address which is "NavList@NavList.net". This functionality is similar to a traditional Internet mailing list: post by email, read by email, reply by email. Most members will prefer the web interface here for posting and replying to messages.

    NavList is more than an online community... more about that another day.
