How LORAN Works

- This is a shortened version of the 1947 "LORAN for Ocean Navigation" filmstrip produced by the Coast Guard as a sales pitch to commercial shipping lines to adopt LORAN (as a both a navigational aid and to assist in distress situations). Updated with a new narration track in place of the distorted period track, the film provides a brief overview of the operational theory behind LORAN.

Why those old instructional videos were so much better than today's shit?
Why can't school be like this?
Always wondered how I worked
Woowww ME TOO
That's how GPS work really not satellites
Always wondered how Loran worked. I'm sure this was super hi-tech in it's day but when you think about how much more accurate GPS is it's no wonder the USA doesn't even bother with Loran anymore. There used to be a Loran tower where I live in south Florida and as a kid I remember always wondering how Loran worked back in the 1970's.
Loran served it's purpose during it's time but technology marches on.
+Randy Evans Surprisingly, they are bringing back an updated version of LORAN as a backup to GPS in ports.
+Randy Evans GPS is LORAN, LORAN is GPS (main difference is Frequency, not operational theory). Notice how there is no accounting for any Earth-spin induced Doppler effect in this animation (and nor is there in any radio or RADAR triangulation system in use today - ask me how I know). Ask yourself...Why? Your brain and your life-long indoctrination through both media and school may make it difficult for you to really understand what I'm saying here, but I know people who worked on LORAN II and other similar systems, and have/had family members with some of the highest clearances in the Intelligence community. They don't want you to think about this question or ask to many related questions...but the truth is coming out anyway, and I have some confidence that a fuller disclosure surrounding these phenomena (and related ones - like the deceptions pulled off by NASA, etc.) is forthcoming. Why, I don't know, but THAT they are coming...I'm quite confident.
+StopMoColorado LORAN is NOT GPS sorry, I am studying navigation. They are similar, but not the same thing. LORAN uses TDOA principal, whereas GPS - TOA. GPS is global, LORAN - is not.
Игровой канал RobosergTV "GPS" most definitely has its roots in LORAN (GPS signals are higher-frequency, for one)...this is even demonstrated in the "credits" for GPS, which refer to LORAN, and other unspecified DoD technology. GPS is most definitely NOT global...just watch 24/7 Flight Tracker over the South Pacific, or listen to NASA scientists explain that the Orion launcher loses contact with Houston over the Indian Ocean...I won't waste too much time with this, anyone who's curious can do more reading on the topic. Your local cell tower is helping to spoof the GPS signals...there are apps that can help you find them (a bit tedious, but possible), you'll soon realize they're terrestrial, not "Geostationary" (which is impossible for more reasons than I care to detail, but impossible nonetheless) and in orbit.
+StopMoColorado I already told about about the differences. I am having exam tomorrow in "positioning and navigation" and I know better, how LORAN and GPS work. They use different methods, have different coverage etc. They are similar, but not the same.
Currently in a Marine Nav. program and it has been noted that Loran is to be removed from the course in the next few years.
This is the FUTURE!!
The inventor of this technology was also a great actress named Lauran Bacall: she wanted a lot of "back call"s with her slave tower at that time:)
A very interesting system
how far is the ship?
I wish I had seen these in Elem. school.
I was interested in space science when I started school, or maybe before that.
I was born in June of 1966.
Loran have nothing with space to do. neither do GPS . :)
Apparently the USA and Canada have ceased using LORAN.
They favour GPS and other satellite navigation means
ToonandBBfan same shit different receivers all done with same towers. Satellites are fake. It's 2017 if you think Earth is a spinning ball, you're still not awake. wake up wake up. time to get up. realize grown ups are just grown kids and we've all just accepted the reality in which we've been presented
wake up wake up
@HiWetcam en.wikipedia.org/wiki/Poe%27s_law
@HiWetcam these people are serious and the problem is they don't want to hear truth.
@@ks90e lol imagine believing that
LORAN proves flat earth. GPS means ground position system so no satellites in space
thats pretty neat ngl
I couldn’t find much information about non GPS RNAV
is there another name of second station 'Secondary' existing?
Yes. Also almost every master stations will have three secondary station named Red,Green, and Purple.
I think they still use this way in navigation system. .It's mean there is no satellites. .
How do you know there are no satellites?
@@Volleyball_Chess_and_Geoguessr It was a system used BEFORE satellites, It was a GROUND based navigation system. The TIME difference in radio pulses were used to create a "grid" like on a piece of graph paper that you could determine where you were on land sea or in the air. My father was one of the first teams to develop and install this system in WW 2.Unlike RADAR, the great thing about it was: the radio signals weren't generated by equipment on ships, or planes they were only RECEIVED. That way the enemy couldn't "tune in" or TRIANGULATE your position and blast the hell out of you. You would simply RECEIVE the radio pulses - observe the TIME difference and be able to plot your EXACT position at SEA on LAND or n the AIR, wherever you were.
My analytical geometry professor just published that on Google Classroom for I doing the homework based on this.
P.S.: I'm Brazilian. Then I speak Portuguese and the text is in English.
Why can't school be like this?
Damn I was pretty important back then
hi loran740, have you become a flat earther yet?
A common mistake was calling Bodie Island "Bow-dee." It does look like that's the pronunciation but it's the pre-colonial spelling for 'body.' As in, _"Dead bodies washed ashore after the ship ran aground in a storm."_
HtF can Loran work on a globe earth?
Same question
Because radio waves travel in a great circle, not in a straight line
@@Justaguy365 at least that's what they told you in school …and some other stuff too
@@Volleyball_Chess_and_Geoguessr a globe earth will need a parabolic loean movement to make sense on a globe... but hey ....i also came here to read comments
@@Justaguy365 , ha, ha, stupid Guy.
Ground GPS
"one is the master, one is the slave"
eLORAN Cancelled -2024
LORAN HAHAHA!
who els TH-cam this to get boat crew qualified
Is the earth flat?
@@Volleyball_Chess_and_Geoguessr No
@@Volleyball_Chess_and_Geoguessr yes
Why are all the flat earthers on this video 💀💀💀
If you think it´s GPS system we use today, then can I tell you for sure it´s eLoran system. There are no satellites in space! Satellites may exist in helium balloons, very hi latitude in the atmosphere, ex. 100.000 feet
you are extremely naive Jon...the weather and other directional information provided by satellites can't be matched by any other service...LORAN doesn't provide photos, that's a big one. Especially a radio-based navigation from WWII...lol
Jon, take your meds!
@@tjweklak lol . They send up 2000 ballons everyday to check weather... wow so stupid people are to day
@@tittentei7331 really Mitt? You think that's how you can watch a hurricane approach with accuracy and warn the residents in time to leave the area? Go back to school, and stop being ignorant...
@Sven3xs So true! And so sad!
Master and slave...typical evil programming
Obviously racist technology.
@@Browningate another name for slave??
Yep.... as suspected GPS based on the similar technologies is mostly ground based. No imaginary floating satellites!
2000 Miles , and line of Sight = Earth is flat.
gaint mirrors!

HF frequencies bounce of the ionosphere you jackass
