Plotting an LOP

This video explains how to plot a line of position for celestial navigation.
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:

Awesome tutorial, thank you for sharing.

thanks for sharing.
i was struggling on how to draw the 3 star fix, but i think i got it now

Awesome love the music adds nautical flare.

I recommend flagging each LOP in the direction of the observed body's subpoint in order to resolve the triangulation accurately. This is a good technique to use because frequently with H-cut LOPs the correct fix position is not in the center of an apparent triangle.

Q. What did the "Old Time" Navigators do before they had pre-printed "Sight Reduction
I've sketched out a short form for myself on lined paper. But what did THEY do, back in say the 1890's?

am I the only one who wondered how you got Saturn sighted at 1339 while the sun is up at 1335? I think it would have been better to do a running fix example 2 hours later.

"Pick an assumed position usable with the sight reduction tables" A whole number latitude was used but longitude seemed seemed arbitrary. What makes a good assumed position coordinate?

[chloeburraston]

Hey question where would you find a position sheet?

[Loukas]

I have one question: even if the time interval between the consecutive altitude measurements is only a couple of minutes (as in the video above), isn't it necessary to assume a new AP for each of the position lines? Cheers.

What was the purpose of the DR point? You didn't seem to use it for anything.

Great video, but the pirate music is really a bit cumbersome. This is a subject dense with information, IMHO the stylization of music really hurts the effectiveness of the video

Please reissue without the stupid music. Really detrimental to concentration and learning. Which Oompa Loompa came up with that idea? Dreadful!
