Talk before October 2006

I have scanned Wikipedia for compass use and navigation and feel that it could be enhanced. My son has prepared a page that he might share with you. Please have a look at it. I will be glad to be the go between. Thanks for all the good work done be your contributors.

Alison Phillips See this page: http://luna.moonstar.com/~acpjr/VADF/Navigation/MapCompass.html

That page looks interesting, note however that it seems to be concerned mainly with land navigation, so it would probably best to make a new article specifically about this (if there is not already one, but I think there is not). If your son's work can be released under the conditions described under Wikipedia:Copyrights, we'll be glad to accept it. Thanks, Kosebamse 12:16, 19 Nov 2003 (UTC)

Celestial Navigation changes...

change relative position.. the stars don't change their position relative to each other. I changed the wording so there wouldn't be confusion.

Determining local noon is very easy, as you are taking your readings you are moving whatever measuring device you have in one direction since the sun is rising. When the sun "stalls" at the top of the sin wave, you know it immdiately because you stop following it and then see it drop below the line on your device.

The reason that clocks were necessary for longitude was so that you knew what time it was at the known port, not to determine when your local noon occurs. It is a time difference calculation, hence the need for an accurate clock to carry the "time" from home with you.

Even before radio direction finders, the radio was valuable for navigation since the time at a given location could be broadcast. Synchronization of clocks on ships with radio broadcasts was an interesting ritual developed to minimize the calculations for calibrating of the clock.

Night time navigation without instruments is much easier than daytime navigation. Polaris is used to maintain whatever head you desire by simply keeping it at a known location relative to your bow. You latitude can be determined anytime you can see polaris. East and west are easily determined with any star that is visible by watching the direction of travel. A clear night was a blessing to the navigator and helmsman. On a clear day, you were largely limited to a single latitude reading at noon.

If you could see any star near the horizon and any piece of land you could determine latitude by the angle the star followed rising or falling.

How much interest is there in the actual formulas for navgation?

Hi, I was wondering if anyone had ever attempted to write a description of and/or basic tutorial for the use of maneuvering boards, and would like to volunteer to do so if noone has. Thanks --nekonobaka

Celestial Navigation

I though this article had too much on Celestial Navigation. I deleted it rather then move it to Celestial Navigation because it seemed like a good article that may didn't need the extra material. If I have lost good info in the process it can be worked back in. KAM 13:48, 11 October 2006 (UTC)

New user Captclbecker just restored a bunch. I think he may have not realized that celestial has its own article and that the details are probably best kept there with a 1-paragraph entry here. Hopefully Captclbecker can comment here and we can work out who will change the article. - Davandron | Talk 14:22, 25 January 2007 (UTC)


Questionable link

Are these appropriate for the navigation article?

  • http://indoorLBS.com/ Local Positioning Systems for Navigation - Complimentary and Alternative Positioning Technologies to GPS]
  • http://www.lbsinsight.com/ LBS Insight] News site on wireless navigation services

Seems like linkspam - Davandron | Talk 23:58, 24 January 2007 (UTC)

Merge of Passage Planning

Passage planning seems to be able to be contained within the Navigation article. The brand-new article doesn't contain significantly more text than was here. - Davandron | Talk 03:00, 6 March 2007 (UTC)

In the passage planning article, I've spliced in some edited text from section 2507 of the 2002 Bowditch wherein passage planning is viewed as an aspect of brige resource management. I've also added some recent legal and technological and removed some information that seems like "how to dr" and "how to take a fix." My original motivation for the split was to 1) open it up for some aggressive editing without disturbing Navigation, and 2) clear the way to incorporate some of the information into Second Mate and Quartermaster. Cheers. Haus42 22:02, 6 March 2007 (UTC)
Agree with Haus42 on splitting and suggest to rather merge the section from "navigation" into "passage planning" --Best, any IP. 07:50, 24 March 2007 (UTC)

Since my original suggestion to merge, Haus42 has done a great job filling out the passage planning article. As such, I here-by revoke my suggestion to merge. Since there hasn't been any additional comment supporting a merge in three weeks, I'm going to pull the tags from both pages. Thanks again Haus42! - Davandron | Talk 00:43, 27 March 2007 (UTC)
