@YellowSubmarine, I am enjoying your mod, but I've seen a strange anomaly I hope can be explained.

• 2100z - Departed Memal sub tent.
• 2148z - Cleared Memal Harbor and ordered a 315 heading at 10kts
• 2349z - Shot Polaris at 56*6.9' elevation @ 20:34:08??

You can see the anomaly is the time of the shot sighting was off by 3hrs 15mins. What am I missing or doing wrong? Is there an adjust ment I need to make?



Standing by.

The angle of Polaris above the horizon is equal to the degree latitude that you are standing on. Therefore at the equator, Polaris is 0 degrees above the horizon and at the north pole, Polaris is 90

Edit: here is a online almanac also a good celestial software is Stellarium to see where polaris and any other celelstial body was in game time and date

31.08.1939

Thank you for the almanac. Also, I love Polaris as its elevation is my latitude and GMT gives me longitude. The problem anomaly I was referencing was...



2349z - Shot Polaris at 56*6.9' elevation @ 20:34:08??


Notice the first number is the time I took the shot, "2349z," but the SH5NewSextant shows the time I took the sighting was "20:34:08" which is 3hrs 15mins earlier. I'm pretty sure I have missed and adjustment, but I don't know where?


Edit: Here is one I use... https://aa.usno.navy.mil/data/docs/celnavtable.php

nice :D thx for the link i am also a celestial navigation enthusiast i never used GPS in my life and also i sail when i am in vacation or i have 3-4 days off from work :D
i drive across Europe without GPS as long haul heavy truck Driver :D

You're welcome. I used to sail an AMF Fantom 14' on lakes, but never had the chance on the seas. I also had a 19' sloop, but never got to sail it because I got sick right after I bought it. Hey a fellow trucker! I drove too and owned my own 1999 Volvo 770 truck. I drove off and on for 20 years. It looked just like this... http://img0129.popscreencdn.com/1810...s-for-sale.jpg

look like this what i drive

Very nice! It looks like fun to drive. :)

I was not aware of any conflict with TWoS Campaign Advance Verifier Testing.
Maybe you guys can fix it. You are free to modify my mod. I developed this mod during unemployment, but with a full time job I don't have the time anymore to mod.
About Polaris, look in documentation 'Additional Information'. Do you get the correct lat/lon with the computed solution?

The short answer is I have read everything, but I may have missed something? I will report back.

@YellowSubmarine, the docs have this,



"Note: Some random objects in the sky are displaced a small distance in the game. For the Moon, Sun and navigational stars the difference is a few minutes but when this happens to Polaris it can amount to several hours due to its closeness to the pole. You can still use the Polaris tables with the computed solution, but do NOT use Polaris for estimating current game UT.

Does this mean I should ignore the time on the SH5NewSextant and use the GMT in game?

FYI - Here is my sextant and case. It is a 1946 Husan (Henry Hughes & Son LTD London) Serial #533149 Certified Dec. 31, 1946. The light to illuminate the scale at night still works by pressing a button on the handle.

Use the time provided by the sextant. Maybe I did not make myself clear.
Here's an example.
Suppose you measure Altair. The sextant shows 17:00:00 UT.
Then immediately measure Polaris. Ideally it should be close to 17 UT as well.
But let's say it shows 18:00:00 UT. If the moon rises at 19 UT. You would be false led to believe it is 1 hour to moonrise when it's actually 2 hours.
But you can still use 18:00 UT for any calculation with Polaris.
I tested Polaris before I uploaded this mod and the time was close to the other stars. So maybe it was an earlier version of the mod. I don't remember.

Thank you. FYI - I will be away from my laptop for a few days. I will test when I return.

I am still unresolved as to why the discrepancy between SH5 GMT and NewSextant GMT. Did I miss something?

We're back from our mini-vacation. Ready to get back to figuring this out.
