We go to the market and buy:
1. The Quadrant. It costs a penny. It is needed to calculate the elevation angle of the observed object above the horizon. Aim at the bottom edge. Switch the camera's sight point (crosshair opacity) from the game menu to one for it to be transparent.
2. The solar compass. Pennies. Do not use it instead of a compass! There are no convenient serifs!
3. Chronometer. It is expensive, about 900 Lions / 9000 emeralds / 1800 crowns. Absolutely irreplaceable!
Don't take a chronocompass, it's complete ♥♥♥♥♥♥♥♥, but it stands like a big ship.

First of all, a little bit of statistics.
A game minute lasts 2.086 seconds or 2 and 1/12 seconds.
An hour is 2 minutes and 5 seconds.
A day is 50 minutes.
The full reserve of vivacity is 45 minutes,
hydrogenation is 55 minutes,
satiety is 75 minutes or a day and a half.
One degree of longitude on the map is equal to 4 minutes of the sun's movement.
1 degree= 90 nautical miles.
Positive degrees lie to the east of the prime meridian
Negative degrees west of 0
The Lag reading is divided by 1.6 to get the true speed of the vessel in miles per hour, it is also Knots.
6 according to the lag, this is 90 miles per day, it is also a degree per day, excluding demolition.
The compass is divided into 32 points. Clockwise from the North - N NtE NNE NEtN NE NEtE ENE EtN E EtS and so on

Further abbreviations: TN - true noon, K -quadrant or its indication, SC -solar compass, X -chronometer, T -chronometer time indication, W -latitude, D -longitude

1. The TN shows the SC. The sun will be in the south, the shadow of the gnomon will align along the south-north line. If the shadow is pointing to the west, it means it's too early. If to the east, then noon has already passed.
1.a. At +-Noon the shadow of the gnomon shows the tip on the W.
1.b. At true noon, we grab K and point it at the middle of the sun. It's blinding, take it away. The reading K is subtracted from 90, (90-K)=W Doesn't exactly work, but there is a way. What if you really need it during the day? If there is no SC, then we check the sun strictly in the south and read K.
1.c. Strictly in TN, we quickly look at T. If X shows less than 12 hours, then our TN happened in fact before noon on the Zero Meridian. So we're in the east. If later, it means in the west. This must be properly understood. The same principle works when we read the Northern Constellation.
The formula for calculating D at TN according to SC and X: (1200-T) / 4 = D Method requires agility, since every 2 seconds of delay the clock hand will count down plus a minute, which means every extra minute is 1/4 degree of error. Be careful!
2. Closer to 7 p.m., we are looking for the Milnead star in the west and a little bit to the south. In the east, in Emerald, the sunset is earlier, so it is exactly darker at 7 and it is easier to observe the star.
At exactly 7 a.m. we read K. K-15 = D
3. The dark time of the day begins. The Northern Constellation is visible in the north. The North Star itself, an analogue of our Polar One, is easily determined by the compass. The constellation consists of 6 stars. We are interested in 4 stars extending in a sickle from the North. The constellation rotates counterclockwise around the North. I call it a Sickle and I can read the approximate time without X on it. Next, you will understand how. That's what I call the stars.: North N, following the crescent N1, then N2, N3 and N4. At some point, you may notice that, for example, N and N4 are aligned vertically. You can check it by picking up K, it will perfectly fit, turn it with a wheel. Or a broom, until you press the RMB it will be vertical.
3.a. N and N4 aligned vertically, quickly read T.
N4 (0848-T)/4=D. For example, you noticed a vertical at 0908. The difference is -20 minutes. -20/4=-5. You are at 5 degrees west longitude, apparently in GRC or AI or Oasis
3.b. N3 (1026-T)/4=D, for example, you checked the vertical in 1007, (1026-1007)/4=4.75 eastern D, you are exactly in DC or NP
3.c. N2 (0039-T)/4=D
3.d. N1 (0158-T)/4=D
3.e. At any time of the dark from dusk to dawn, measure the height N using K= W
4. Strictly at 0000, that is, at midnight, count the stars of Witen, you will find it extreme on E in a constellation very similar to our Cassiopeia, in the form of the letter M. The star is the far right from the bottom, the end of the letter M. In the west it will be still low, in the east at midnight at zero - high.
The formula K-33=D, for example elevation 33 says that you are on the prime meridian, 35 +2 east, 29 -4 west. You can check between measurements N3 and N2. Quite a lot of margin of error, an inconvenient way.
5. At 0520 in the morning, the Oriens star will rise in the east and little bit to the south, at exactly 0520, be on deck like a bayonet and measure the height with a Quadrant. This is the most difficult measurement in the selection. The further west you are, the darker it will be in the east at 0520, the less light there is for observation, but at the same time the lower the star above the horizon! In Al-Ankh at 0520, Oriens will be literally at the horizon level. And the Sun will shine on her in Emerald. The star is well visible from the edge of the screen or through a telescope.
The formula K-5=D

In total, we have 11 ways to read coordinates.
There are 3 ways to read latitude, 8 ways to read longitude. 3 in the daytime by the sun and 8 in the dark by the stars.

Briefly again. The memo.
