Terrestrial/Celestial Spheres Coordinate Systems Tutorial
Вставка
- Опубліковано 5 лют 2025
- This video explains the coordinate systems used in celestial navigation, with an overview of the terrestrial and celestial spheres.
This video is part of a series that teaches celestial navigation using techniques that have been used for centuries. In this course, you will learn some basics needed to find your location using a sextant and elementary math.
This course is free and available to everyone, and should take less than two hours to complete.
The course is hosted by Vanderbilt University at:

a very nice video. I'm a navigating officer on a domestic ship near coastal. this tutorial
will help me to take an unlimited exam.
@@che0 Hi friends, oh no, I have never sailed around the world,
I only sail all over Southeast Asia. but I am very interested for study Celestial navigation.
@@che0 Yes, my friend, I feel like what you think
@@che0 Navigation is based on a well-established knowledge of spherical Earth.

What you sailing, Costa Concordia?
Was almost a great educational video,
Hey..
Never heard of a Celestial Prime Meridian. But perhaps I have forgotten or just never cared to pay it any attention. When I taught celestial navigation, the First Point of Aries was the reference on the Celestial Sphere since GHA is a Terrestrial reference not a Celestial one. And of course we both know we use the GHA to plot the geographical position of a body, this information is already converted from SHA to GHA and tabulated in most of our almanacs. We know this is done to make significance of the position of a celestial Body being placed on earth bound coordinates rather than listing it as Lat/Long, and possible confusing information.
Great video and great music, but they don't work together. The music volume is too high relative to the other audio and the base tones clash. The result is very distracting and makes it quite difficult to pay full attention to the content.
3:30 Where can I see that the almanacs tables Re really derived from spherical trig?
GREAT 👍
Just noticed you put "Drunken Sailor" as the background music.
Why did everyone in the comments got so pressed about the music 💀
You should give example.
He’s not going to take the music out so stop demanding that he does. He put it in for a reason. Because sailors used these calculations for travel and navigation. It fits and if you don’t like it that’s fine. But you’re along for the ride and not paying for it. Ask yourself this. It may sound silly to me but does that really make him unprofessional?
Yes. Damnably annoying and given the complexity of the topic unprofessional.
@@Docsailor1 There are much better intro videos on the topic. It's a shame to put so much effort into something to have it be so bad. On the other hand, this frightful video does inspire me to get my crew to sing "...what do you do with a drunken sailor...," as I reach for my sextant.

Please reissue without that stupid background music.
It destroys concentration and makes the whole thing gimmicky. Or if you want to move away from being a serious educational provider then add some dancing cheerleaders and twerking celestial bodies to make it even more "cool"!
A really good course, clearly created with with lots of effort and thought ruined by adding stupid background music!!! I will find another provider to learn celestial navigation.
i agree, the sound is terrible
I thought the exact same thing. This video is very complicated and all of a sudden a note in the music took my brain hostage. I wish there was a music mute on UA-cam.
An old sea shanty seems appropriate given the history of celestial navigation and seamanship.
Godamn guys is everyone having mood swings in the comments?💀💀 it’s just some music
Sorry to pile on, but I have never had to struggle so hard to focus on the main content of a vid with such annoying music in the background. Kudos for effort, but I'll look elsewhere.
Elevation angle measurements require a flat earth. Welcome to flat earth!!!
listening to stock background music .. err no good ..
This is surprisingly, disappointingly bad. What a wasted effort. I guess you get what you pay for.
total solar eclipse cannot occur on the terrestrial globe ,why?
