Good idea.

This means
having a very good idea of your course. This way, with a single LOP
and your known course, you can get your position ...

You need to brush up a little on elementary piloting. Knowing the vessel's
"course" and crossing it with a single line of position does _not_ result in
a fix. In fact it doesn't even result in an EP.

Are you confusing "course" with DR track?


Call it what you want, I know my geometry and trig. I live and breathe them.
