Knowing the military they will have you watch it all in one sitting with only a few breaks and expect you to know it. Our method in the Marines was throw guys into a place with briar patches and cliffs at night time and give them a time limit to find boxes with numbers on them. If it dont make em good at navigation it will sure make em mean.

I was a USAF Navigator in the early 80s. I remember watching this on 16mm film. Everyone laughed at HoMoTo! This is the best video I have seen. I’m now learning to use a marine sextant. Concepts are the same but use the real horizon rather than a bubble.

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

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.

¿Any idea how to locate the first aries point from any place you are on earth? Is for the purpose of practicing. Maybe some DIY clinometer gadget, that help me to locate where is the vernal point, and after that, finding a star by it´s declination and AR? Or maybe a simpler method? By the way, i like your tutorials, they are very good!

@TheWindigomonster6 жыл бұрын
marshalcraft exactly! GPS uses the exact same principals, except with man made satellites acting in place of stars
@ozzidan5 жыл бұрын
Yes, same principle but different mathematics. With the use of a sextant, you are measuring the angle to calculate the distance you are from the GP of the heavenly body. GPS works on a signal sent from the satellite and your GPS is actually a receiver. Your GPS will receive the signal and decode it, and it works on the principle of the speed / distance / time equation. Your GPS knows the location of the satellite, the speed of the signal and the time in which it takes to get from the satellite to your GPS recieved. (there are some errors in which your GPS will apply (clock error, drift error) The GPS now now knows the exact distance you are from the satellite, and just like a single observation with a sextant - with one satellite you will have a circle on the earth. 3 satellites are required to give you a position fix. (however GPS uses 4 (see pseudo range)
