From the famed missile-guidance-systems tutorial: "The missile knows where it is by knowing where it isn't." Now I believe with 99% certainty that there is a 75% chance I am not where I think I am if I think I am within the cocked hat. And with diminishing probability I can be anywhere on the surface of the earth EXCEPT in the clocked hat 3 out of 4 times. Also, if I have used celestial objects within a 180 azimuth range, AND I know of personal or systematic errors then I bisect the LOP's to find my position which almost certainly will be outside the cocked hat. Also that bridges and underpasses may ice up before the road surface. "The sublime and the ridiculous are often so nearly related that it is difficult to class them separately. One step above the sublime makes the ridiculous, and one step above the ridiculous makes the sublime again."--Thomas Paine The academic analysis, now a running gun battle in a corner is enlightening. Certainly a warning to the prudent navigator to not bet the ship, her cargo and souls on the fix if potentially in harms way. In the bigger picture is the goal to coastal pilot and/or find your lobster pots via cel nav? Or perhaps find your way across a large expanse of water and make landfall then work on your short game? In either case, wayfinding and other clues (a prudent navigator makes use of all available information) might be useful. As this thread continues on ad infinitum, please keep in mind the following: "I used to be into necrophilia and bestiality....but then I realized I was just beating a dead horse.--The Cellar Restaurant, VA Bill --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to NavList@fer3.com To , send email to NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
