    Google Globe
    From: David Pike

    Has anyone tried to pin the North and South Poles in Google Globe yet?  The South Pole is easy.  There’s a tiny little white dot.  The North Pole is harder.  Disappointingly, there isn’t a scaffolding pole sticking up with a flag on it.  However, if you look very carefully in satellite, while turning the globe slightly you’ll see a number of very dim ‘2019 Google’s in concentric circles about the pole.  Also, very close to the pole there are some lightly paler light blue circles about the pole.  The distance from my office at 53N 10’N to the pole is 4096km for a spherical Earth and 4109km for a WGS84 Earth.  The Google Globe distance, as near as I can measure it is 4097km, so it looks like Google are using a spherical Earth for Globe.  Therefore, there are possibilities for playing around with celestial PZX triangles on it.  Who’ll be the first to try?  DaveP

    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.
