Great elementary introduction to celestial navigation. I have to admit that I am affected by Dyscalculia. Numbers seem to come and gone like grains of cool-aid powder. At 62 I have read many books on how to Celest nav and of late watched several you-tube vids for the last ten years and it is still like looking at a muddy lake and trying to pick out a single silt particle to me. I am fascinated by Celestial Navigation but its so far beyond me. I have developed other super powers, but number evade me. Jim Rodgers

@iveneverseensuchbehaviorin53677 ай бұрын
Polaris isnt exactly above the top of our planet and its movement is measured year by year. Every night it circles the north celestial pole like every other star in the northern hemisphere. there is even closer stars to the pole than Polaris just not as bright.

I did the math for getting a position from 3 observations alone. At first I tried just finding the intersection of the planes that the circles of equal altitude live in, but that can give your position with an error of a whole degree across earth's surface or more (60nmi). To get accuracy, you can find where the circles of equal altitude all nearly intersect. My result involves too much computation to do without a computer program or spreadsheet though, and I wouldn't want to have to do it by hand even with the aid of a calculator.

The sextant only measures angles, like a ruler measures length. It does not prove or disprove anything. It is the calculations based on the astronomical tables and spherical trigonometry that give the position, and that does not work for a flat earth. The GPS system is also based on a spherical earth as the US Navy who operate that system will tell you. You really haven''t a clue about the subject, so why don't you go along to the nearest naval base and ask how it works? Meanwhile, have a look at this /watch?v=9IIMrk0QrIY&t=2s

Please explain how you get an elevation angle with a curved baseline at your feet? 😂 Earth is flat George. There isnt anyone antipodal to your position sitting on a toilet taking a crap UPSIDE DOWN. Oh and GPS doesnt prove ANYTHING. Just like google earth it fails to show ANY curvature or 8 inch per mile squared. Nope it shows the same elevation for miles. Also this video shows that they use the celestial sphere equator. In other words they had to cut the sphere in half and use a FLAT PLANE to do all the calculations. Why would you have to do that? 😂 Because they manipulate the math to fit a sphere model that doesnt represent reality. Earth is flat!!!!! Wake TF up already. You know what.
