Navigation is the process of monitoring and controlling the movement of a craft or vehicle from one place to another. It is also the term of art used for the specialized knowledge used by navigators to perform navigation tasks. All navigational techniques involve locating the navigator's position compared to known locations or patterns.
In the European medieval period, navigation was considered part of the set of seven mechanical arts.
1530s, from L. navigationem (nom. navigatio), from navigatus, pp. of navigare "to sail, sail over, go by sea, steer a ship," from navis "ship" and the root of agere "to drive" .
The latitude of a place on the Earth's surface is the angular distance north or south of the equator. Latitude is usually expressed in degrees (marked with °) ranging from 0° at the Equator to 90° at the North and South poles. The latitude of the North Pole is 90° N, and the latitude of the South Pole is 90° S. Historically, mariners calculated latitude in the Northern Hemisphere by sighting the North Star Polaris with a sextant and sight reduction tables to take out error for height of eye and atmospheric refraction. Generally, the height of Polaris in degrees of arc above the horizon is the latitude of the observer.

Plot
Five years after the events of the Babylon 5 series, a technomage named Galen predicts an imminent attack by the Drakh, the old allies of the Shadows. Through dreams, a thief, a captain, and a president are brought together to head them off. The president is John Sheridan. Because of his irrational behavior, Sheridan's friends begin to wonder about his sanity. It's up to all of them and two prototype battlecruisers, the Excalibur and the Victory, to stop the fleet and their planet-killer. But is there more to the Drakh's plan?

Captain Elizabeth Lochley: You're asking the impossible.::President John Sheridan: Then I am asking the right person.
[last lines]::President John Sheridan: Those who command the Excalibur will never stop, never give up, never slow down, until a cure is found. We will take any help we can get, wherever and whoever it comes from. Because this is a cause that surpasses borders and differences and distrust. This is a mission about the survival of Earth itself. What we do over the next five years, here and at home, and across the darkness of between the stars will determine the whether an entire world will live or die. It's a fight we can't afford to lose and we won't. We won't!
Galen: No, not a dream, a nightmare. And if sometimes dreams come true, what of our nightmares?
Leonard Anderson: [after Dureena extracted a data Crystal from a Drazzi "skin pouch"] Hey, lady! Dureena! Listen! The only thing valuable I carry on me is my *watch*! I want you to know that in case that ever comes up in the future. OK?
Michael Garibaldi: [Drake has a PPG pointed at Garibaldi] Because if you are going to blow my head off, I suggest you do it right now or I am going to tear your heart out. And if you do shoot me, the rest of my people will be all over you. And what they'll do to you is worse than anything I could dream up in a thousand years. And I can dream real dark.
President John Sheridan: Looks like you won't get your chance to shoot either of us.::Dureena Nafeel: I've grown accustomed to disappointment.
[first lines]::ISN Reporter: Meanwhile, on Earth and Minbar, preparations continue for next month's celebration marking the fifth anniversary of the Interstellar Alliance. Aside from one brief conflict with the Centauri Republic early in its first year ISA President John Sheridan has delivered on his promise to maintain peace among all its member worlds...
Michael Garibaldi: [to Sheridan] You were looking at gibberish for 20 minutes. Look, you wanna do that, swing by my place some time, and I'll show you some 20th century television.
Galen: Fear makes wise men foolish.
Twenty thousand leagues under the sea, without a paddle. A pair of civilians are the only hope for a nuclear submarine stuck thousands of feet beneath the polar ice cap.
Laura Dyson: What was that about the soul travelling that you were mumbling when we were sitting in the dark?::Rick Postley: Nothing.::Laura Dyson: And you did it when we first went under water.::Rick Postley: Forget it.::Laura Dyson: Do you quote any poet, or just Walt Whitman when you're nervous?::Rick Postley: Just Whitman. Okay?
Harry Rheinhartdt: Look, look at that, look at the size of that keel, the ice, see it? Must be a hundred feet.::Rick Postley: And, it's shaped like your nose.::Harry Rheinhartdt: And it's twice as big. I'm naming it the Rheinhartdt Keel.::Laura Dyson: You're naming your nose the Rheinhartdt Keel?::Harry Rheinhartdt: No-no-no, my nose is called Gerald.
Commander Kirsch: While we transport Dr. Rheinhartdt and Mr. Postley to their designated research area, we'll try to accomodate your whale-watching.::Laura Dyson: Actually, it's a little bit more complicated than whale-watching.::Commander Kirsch: Well, I'm sure you wouldn't be here unless you called it "Cetalogical Recognition Factors in Subaqueous Environments."
Rick Postley: So then, what is your position on the current role of the military, Captain?::Commander Kirsch: I was first in my class at Annapolis. I don't want to get into a discussion of strategic theory with a civilian wearing an earring.
Harry Rheinhartdt: What is that? It smells like peaches.::Rick Postley: Well I don't know anything that's good for you that smells like peaches that isn't peaches.
