Gosh. I had no idea there was a satellite navigation system predating NAVSTAR GPS - and it ran concurrently with it until 1991 (and for other purposes until 1996). Cool.

One of the opening scenes of James Burke's "Connections" (Episode 4 "Faith In Numbers") series shows the TRANSIT nav sat in operation; I think that's what's being shown in this video ...

My takeaway is that their line printer paper bill must have been pretty high.

[@colbytafrica]

I would say so! This stuff is cool though. Before "all the smart" people, to quote some teenagers, invented iPhone, SnapChat, Instagram, and Twitter, there were system's like this where, "oh, ionospheric distoration?" We got that covered. "Those pesky masss distribution problems of the Earth?" Sure, we can do that too. Amazing.

[@WalterFabian]

Excellent. Thanks for the continued effort on preserving this material.

[@ComputerHistoryArchivesProject]

Walter, thanks very much for your kind words of support. I enjoy doing what I can to preserve bits of history and share with those who may appreciate it. ~ Thanks for watching.

[@bhk7az641]

We used it on our Polaris submarine during Cold War patrols - 67- 73

[@enilenis]

Thank you for this channel, and for preserving history. All videos here are fascinating.

[@ComputerHistoryArchivesProject]

Hi enilenis, thank you very much for the kind words. Glad you are enjoying our channel. We certainly appreciate you feedback! ~ Victor, at CHAP

[@BobDenny]

I used the 7094 at U of Arizona Engineering. We also had the CDC 6400.

[@ComputerHistoryArchivesProject]

Nice hardware!

[@miguelferreiramoutajunior2475]

Thanks for preserving and sharing.

Miguel Ferreira Mouta Jr., Thank you very much.

Ultra High Speed Magnetic Tape... sounds totally silly these days. But really interesting stuff! Thank you, CHAP, for sharing this video.

[@ComputerHistoryArchivesProject]

Glad you enjoyed it. Thank you for the kind words. ~ Victor

[@stargazer7644]

Many of your enterprise and cloud computing systems still use "ultra high speed magnetic tape" for backups.

[@JavierAlbinarrate]

For those interested, the doppler shift method of positioning can also be used in reverse, with a fixed frequency transmission in land and a variable frequency being received by the satellite. This was used for example with the MH370 Malaysia Airlines flight, using the recorded SATCOM signals.

[@stargazer7644]

This is also the basis of how the COSPAS/SARSAT search and rescue satellite system finds people in trouble.

[@ThunderAppeal]

I bought one of these things on ebay, its still up there somewhere from what the paper work says. Glad I found this video, now I can figure out how to use the thing.

[@P-G-77]

Thanks for this.... VERY NICE WORK DONE.

[@ComputerHistoryArchivesProject]

oOo, Thank you~.

[@jakobole]

So, a kind of early GPS - lovely!

18:13 They talk a lot about 'injection.' Today we call it 'upload' and 'download.' I like injection better.

Nice music.

At 5:40, a 60's version of GPS.

[@MasterMindmars]

Very good

Perhaps I missed it, but it appears the accuracy of this system was never stated.

GPS. Looking into the nanoscope back through time, Let's zoom in to a small micro piece of the real estate that's inside your cell phone on a tiny piece of the phone chip that assures you're never lost

[@markelowitz8948]

When was the two-line element set format first used?

[@stargazer7644]

It was developed in the early 1970s. It was a NORAD standard that was used with punch cards. Each satellite used 3 cards, one for the name and other data that didn't change, and the other two for the two changing keplerian element lines.

Is it the one that sings daisy?

[@ComputerHistoryArchivesProject]

Yes, if you "google" IBM 7094 and Daisy Bell, you will get the full story.

[@swainscheps]

26:09 ‘hyperbaloid’ Your challenge is to work that word into a sentence tomorrow.

[@stargazer7644]

Hyperboloid. From hyperbola. As in hyperbolic navigation.

[@paulcheek5711]

everything great today started in the 60's

[@americancitizen748]

So Earth looks like a potato from space? ;-)

[@paulcheek5711]

and they made beautiful cars then also

[@willharry6791]

Yeah, those were the days of fast cars and hot women, or was that hot cars and fast women. I can't really remember for sure.

[@Trev0r98]

Far from "real-time" computing and astronavigation. Relied too heavily on "sneaker net" (transporting and loading tapes, then mainframe DP / analysis).

[@ComputerHistoryArchivesProject]

Yes, true. and I bet if today we called it "running shoe net" it would loose some its charm. Thanks! ~ Victor

[@RCAvhstape]

The users on the ships got a navigation fix within minutes of receiving the signals, so for them it was near realtime enough. As for all the back end stuff with slow data transfers and computing times, all that stuff still gets done for satellites today, except it's faster, uses smaller equipment and fewer people, but the laws of orbital mechanics don't change: you still need to collect several hours worth of data in order to accurately compute a satellite's orbit. Since you are therefore in no hurry, the slower technology wasn't the key factor in the delay to begin with. As long as the user could get his nav fix fast enough and with confidence the system worked fine.

[@andrewsmactips]

As we used to say in the ‘60s: This is as real as it gets.

[@canusakommando9692]

GPS. Its been in the works for 60 years at least. Since the Boomers.

[@stargazer7644]

GPS is not doppler based, it is TDOA based. This was GPS's predecessor.
