Everything is flat and level. No curvature at all. That's why it works. If it was a ball you wouldn't be able to accurately determine a ground position.
Irregardless of the shape of the Earth, this would work. In the round Earth model the curvature starts way, way beyond what you can see with the naked eye.
An easy way to prove the Earth is flat is to get a huge telescope. If you can see Mt. Everest from the USA Earth is flat.
Now that you're back to (re)posting your flattard bullshit, why don't you answer why there are star trails around a southern pole? There's only a north pole in Flattard Land, but there are trivially two poles on a spherical Earth:
You didn't answer me though. How do you get an angle of elevation from a curved baseline? The earth has to be level in order to utilize a sextant to navigate.
The earth has to be level in order to utilize a sextant to navigate.
No it doesn't, retard. Watch the video. He takes the angle between the horizon and the sun. As long as the horizon is at a consistent distance, you will get consistent answers which can be used for celestial navigation -- which relies on charts based on a spherical Earth.
The horizon is level and is a matter of perspective. It is not geometric. The celestials being used to navigate are thousands - hundreds of thousands of miles away. You have to assume that the horizon plane extends all the way out in this distance in order to utilize Pythagoras theory to triangulate the Ground Position.
This would be impossible on a ball, especially one that curves away at 8 inches per mile squared.

Perspective is based on straight lines of sight, retard. That's basic geometry. It's not some magic word that you can use to fit any flattard model.
The celestials being used to navigate are thousands - hundreds of thousands of miles away.
In reality (as in not Flattard Land), about a hundred million miles for the sun, and trillions of miles for the stars, but the exact distance doesn't matter for this discussion. Yes, they are very far away, orders of magnitude farther than the distance to the horizon. But so what?
You have to assume that the horizon plane extends all the way out in this distance in order to utilize Pythagoras theory to triangulate the Ground Position.
It's LINE OF SIGHT, flattard. Just draw a straight fucking line to the object from your position. It's not magic. It's not mysterious. It's basic geometry that you can test on the small scale to the large scale. And it works.
This would be impossible on a ball, especially one that curves away at 8 inches per mile squared.
We live in 3d space, flattard. The sextant measures the angle between any two objects. It could be the top of a hill and the sun. As long as the horizon is at a fixed distance, it doesn't matter whether it's from a curved surface or a flat one -- you will get consistent answers on the angle between the horizon and the celestial object.
Hey retard. You don't understand perspective or celestial navigation at all.
Perspective is based on straight lines of sight, retard. That's basic geometry. It's not some magic word that you can use to fit any flattard model.
It only works on a flat earth. You can't locate a ground position from thousands - tens of thousands of miles away on a curved surface you actual fucking retard. Your ground position would be on the other side of a ball lmao
In reality (as in not Flattard Land), about a hundred million miles for the sun, and trillions of miles for the stars, but the exact distance doesn't matter for this discussion.
No they aren't you fucking retard and that actually makes it WORSE for you if they were. How are you triangulating a ground position over the horizon if its bending away from curvature. Your ground position would be on the opposite side of a ball.
It's LINE OF SIGHT, flattard. Just draw a straight fucking line to the object from your position.
Only works on a flat earth you retard. You have to calculate the angle of elevation to work out the Ground Position of the celestial body, which will be thousands of miles away. After 1000 miles you already lose 130 miles to curvature.
It's not mysterious. It's basic geometry that you can test on the small scale to the large scale. And it works.
Go ahead and demonstrate this with a small scale.
We live in 3d space, flattard.
No shit sherlock, you love trying to make yourself sound smart in an attempt to cover up your pure retardedness.

Holy fuck you are actually fucked in the head. It only works of a horizon this is what the HORIZON MIRROR is for. You don't line the horizon mirror up with a curved surface or a hill you absolute fucking retard.
Traditional sextants have a half-horizon mirror, which divides the field of view in two. On one side, there is a view of the horizon; on the other side, a view of the celestial object. The advantage of this type is that both the horizon and celestial object are bright and as clear as possible.
Hey retard. You don't understand perspective or celestial navigation at all.
You're speaking into a mirror. The ancients and modern day sailors who used celestial navigation weren't flattards. They understood the Earth was a sphere and used that knowledge to navigate.
It only works on a flat earth.
Wrong, flattard. We live in 3d space. Even your delusional Flattard Land is based on 3d space. Perspective works on line of sight in 3d space. The shape of the Earth has nothing to do with it.
How are you triangulating a ground position over the horizon if its bending away from curvature.
It's not triangulation, flattard. If you actually tried to understand how sextants work, and how celestial navigation works, you'd understand. Sextants measure the angle between any two objects. They are a protractor.
For celestial navigation, they measure angle above the horizon. I linked to a video with a sailor showing exactly how it's done. If you know the date and time, you can determine your location on Earth using angle above the horizon for celestial objects. But such star charts are based on a spherical Earth, not Flattard Land.
That's why I keep asking you to show the star charts for Flattard Land. While you're at it, explain why the southern star trails around the south pole. The south pole isn't a thing in Flattard Land. You're living out a delusional fantasy, and rejecting any and all evidence that isn't in accordance with it.
Go ahead and demonstrate this with a small scale.
Oh, more demands from the flattard. What happened last time I fulfilled your demands? You asked me to explain the star charts for spherical Earth versus Flattard Land, and I obliged. I even drew you a picture. Then you ran away again like the little bitch you are.
Try learning something for a change instead of just repeating flattard talking points. Get a compass, a ruler, and draw some stuff.
Holy fuck you are actually fucked in the head. It only works of a horizon this is what the HORIZON MIRROR is for.
Sorry, retard, the sextant is a protractor. It works on any two objects. It's just that its main use is to measure the angle against the horizon. But you can point it any two objects and it still works. The principle is the same.
Maybe if you actually tried to understand how it works, instead of hyperfocusing on the word "horizon", you'd understand. But you might just be too stupid.
Traditional sextants have a half-horizon mirror, which divides the field of view in two. On one side, there is a view of the horizon; on the other side, a view of the celestial object.
The "view" is whatever you point it at. Typically you point the bottom arm at the horizon, and the top arm at the celestial object, but you can point it at any two objects. That's a protractor. The only clever part is the mirrors allow to see both objects at the same time, and when they line up, that's your angle. WATCH THE VIDEO.
Notice how I already knew you were going to talk about a parabola. This is because globalists don't know how to do math. So you copy and pasted an anti flat earth talking point that relies on you globalists not double checking your math.
A parabola is a U shaped symmetrical curve. Show me how 8 inches per mile squared formulates a U shape
