The Omega Navigation System (1969)

This 1969 U.S. Navy training film describes the technology and science behind the Omega Navigation System, used for long range navigation by military ships and aircraft. Source: Naval History and Heritage Command, Photographic Section, UMO-41.

I remember when Omega system status used to be broadcast at regular intervals via WWV.

[@forrestmiller4055]

I used Omega for aviation long range navigation in northern Canada in the 90's just prior to GPS arriving on the scene. It worked very well for getting us close enough to use ground based approach aids. It worked far better than the dead reckoning we used prior to that. Now we use GPS and LPV approaches which pretty much do away with ground based approach aids. I really find it amazing how our navigation progresses over the years.

hi forrestmiller, have you become a flat earther yet?

[@johnwells1015]

The beginning of my airline career we began with Omega Navigation and worked our way through LORAN, Inertial Navigation, and GPS navigation systems.

[@jimboke6yb]

it seems like a slow motion long wave length version of GPS to me. Loran and VORTAC somewhere in the middle.

[@porcovasco]

Fascinating

[@alanspicertelecom]

Actually used this onboard ship in USN back in the late 70's to early 80's. Remember Dead Reckoning? How fast are you going ... where you think you are going to be in 1/2 hour or 1 hour? Good Luck!!!! Shoot sun line at noon time, and stars in the early morning hours. Also Loran C radio navigation. They just put satellite systems when I was getting out in 1981.

[@shrivatsankchari1729]

We learned omega today in gps class. Cant believe Im actually talking to someone who used it!

[@alanspicertelecom]

@@shrivatsankchari1729 Yes, receiver was in small CIC just off the bridge. When standing navigation watch, I think every hour, go get the numbers for the Lane Count from the machine. And the lanes already on the special Omega chart on the chart table. Plot the LOP's from the numbers and mark a fix. I'm thinking maybe we wrote an "O" or Omega as the type of fix. This was 100 years ago so ... :-) :-) Really 40 years ago.

@@shrivatsankchari1729 I spent ten years of my career working as a VLF engineer for the U.S. Navy, and worked directly with some of the very people who actually designed the OMEGA system.

Is there such movie about Loran C?

very interesting video....this should be still used as back up.......

what did he say at 3:10 and 4:16? i think they are cut or something

[@yugos.oficial]

classified information related to the intensity of the signal I guess.

[@user-hm2gb6pm6b]

Useable signals

[@dtiydr]

Wonder how many MW they put out.

[@davidfern5864]

Each station had a transmitter power of approximately 10 kW.

[@stephenbritton9297]

Cause LORAN's not good enough?

[@wellinformed8998]

LORAN required many more stations and did not provide world wide coverage and was more expensive but it was much more accurate.

[@AM-in8gh]

Epic find. And people still think we use satellites.

[@KirkHermary]

We do

[@jadbiz]

@@KirkHermary we dont!! Satellites is a lie . Satellites are so far away that the radio signal would lose to much power . we can do navigation system with ground antennas it's easier, faster , less expensive and more accurate.

[@guyintenn]

@@jadbiz Actually, your intellect is a lie. Can you give me the formula to confirm your thesis that radio waves would lose too much power from a satellite? What is it that I see with my naked eye, binoculars, or thru my telescope? I have seen the ISS, China's Tiangong-1, rows of Starlink sats, and back in the day, Iridium satellites. I have seen these and more, many times. So what am I looking at?
