need a bit help on figuring out true position under real navigation

[Wolfcat]

I watched a few videos on real navigation, but none talked about how to manually figure out your position. Most simply ask the navigator for the fix. But AI always has some error. Is there any way to do this manually yourself?

Hey wolfcat. It’s called dead reckoning. Knowing your speed, and watching the stopwatch you can roughly determine your position on the map! Of course, limited by pc, it’s impossible to determine Course Made Good, And such. I have a video on dead reckoning. If you wish. Click my signature.

Dude, ur channel is so messy. U have SH3 and Sh5 stuff mixed together. Can't you create some playlists to organize things. It's all good. Just busting your chops. Nice video. But I am more interested to learn about celestial positioning. I haven't been able to find any good ones online. Also, in your video, you mentioned you would do another video on tactical deck reckoning, but I haven't seen anything in your library.

Celestial navigating is difficult since it is not modeled well in the game. The sextant used is not even doing it correctly, but through the limitation of the game. The SH3/5 videos work for both games.

I'd be happy to help.

Sure, show me. very interested to learn.

Well, detailing the whole process would be a bit lengthy to post here (but I can do that if you like). Is there something in particular you are having trouble with?


Also, keep in mind that several members here have come to the conclusion that accurate celestial navigation cannot be done in SH. (I don't know because I don't play it.) But if you learn how to do it, you can decide for yourself.

Hi W
Just change the Real Navigation settings in TDW's OFEV so the navigatior gives you what you want.
For example the default error is 5,000 meters just change it 0 and you are on the money.

Aloha and a happy new year to all of u....
u can calculate by yourself the position using the sextant from the game, but it's not 100% accurate...there is some factors for example like the high of your eye's sextant index error and more...
in SH5 is only 1 thing done perfectly with no bugs and that is the celestial sphere/body's... they are really accurate... if u don't believe me install Stellarium from here and use the same date hour location as in SH5 and u will be amazed

btw my Real navigation thread is messed up because i lost my all files from a server and now i am working/looking to fix this

Another quick one. So celestial positioning can only be done at night? I thought you could also do it in daytime based on the position of the Sun.

A typical day in the life of a navigator is a morning fix at dawn using stars/planets, then a mid morning sun sight (rendering only one line of position or LOP). Then a noon latitude sight for a running fix (DRing the morning sun LOP forward). Then an afternoon sun LOP for a running fix (DRing noon line forward). Then an evening fix using stars/planets to tie a bow on it.

for better understanding the celestial navigation watch this video series it's very well explained there

Sjizzle, can you please explain how do you do measurements when measured object is higher than 20-25 deg? How do you eliminate possible errors due to boat instability since we don't have classic sextant double prism view implemented in the game?
