The APG - Apollo Guidance Computer
      #430106 - 09/05/16 06:19 AM

I ran across a post and subsequent YouTube videos. While we've been told how crude the Apollo computer was, I've never know just how crude.

The Charming Genius of the Apollo Guidance Computer talks about some of the now-common software concepts that were invented to build the AGC.

Moon Machines EP3: Navigation Computer starting at 4:55 has a nice segment on the first airborne inertial navigation system - and how things started to go wrong.

Hi Russell,
Thanks for the links. There went a couple of hours<g>.

I liked that early Inertial Reference System they hoisted aboard the C-97.

As technology evolved within the world of aerial mapping we started attaching mil grade Inertial Measurement Units (IMU) to each of our sensor systems. About the size of a coffee cup but at about $80K each. Being the navigational hart out of a cruise missile we couldn’t take them out of the country without permission slip from the Department of State. Revolutionized how things were done in the industry and was a critical component that allowed development of LiDAR equipment.

Regards,
Tom Charlton

Also use those small units in pipeline inspection pigs.
