Ever wonder how Saturn V "knew" exactly where it was pointing at launch?

(1/1)

smartcooky:
Well, wonder no more!

The phrase "Guidance is internal" at T minus 15 seconds was one of the most important call-outs in the Saturn V countdown, and this fascinating short video with excellent graphics explains why.




Its the minute details like this that show just how complicated it is to send rockets to the moon.

Zakalwe:
Excellent video!

Kiwi:
Thanks, Smartcooky. I particularly enjoyed this little bit:
0:05:46  …it could align the gimbal to within one-thousandth of a degree.

I guess that's about near enough if I want to know in which way I'm pointing. :-)
