Me earlier: "This method for determining north with known watch time will work anywhere on Earth, and it will give compass direction within ten degrees if you're careful about setting the angles." I had managed to convince myself previously that there were no "cases", but I'm confident now that there are. So how do we deal with the ambiguity (only two cases)? Anyone have a simple way of expressing it? -FER --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to NavList@fer3.com To , send email to NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
