virtualagc VS CygnusX1

I don't think that's a great example.

For instance, I can step through and even modify that code using tooling like AGC emulators like this one http://www.ibiblio.org/apollo/#gsc.tab=0

What makes it open source is access to the same level of source access that the original developers worked in.

That's what's missing here. Mistral's engineers do not simply open this binary in their editor to do their job.

Glad you're enjoying the videos! I'm Mike from them. :) The Apollo 14 code I linked above was reconstructed in the same way as Luminary 69/2, but the process was far, far too involved for a video. Like I said above, I probably won't be much help with math, but I'd be more than happy to assist with finding documentation or navigating AGC code whenever you want!

The fact that all the information about the computer and software is public and you can verify it yourself like thousands of people have. https://www.ibiblio.org/apollo/

If you’re curious about the the technical specs of the AGC check out Ron Burkey’s website, it’s even got the source code for you to see for yourself: https://www.ibiblio.org/apollo/

Of course you should be able to tell us because all the hardware architecture and software can be found here. So you must have fully reviewed it and located the issues. Right? Than please point out where the error is.

It had manually encoded ROM in the form of "core rope memory", which is pretty wacky, but it was a digital computer. In fact, it was the first IC computer.

You can learn way too much about it and even operate (a simulation of) one here: http://www.ibiblio.org/apollo/

A thrust vectoring rocket! It was my sanity project during the pandemic. Flew many times and even flew two stages with slight software mods:

BPS Space is what got me into building my own thrust vectoring rocket during COVID lockdowns.

It was super fun to bring together lots of different disciplines and skills. 3D printing, software, soldering, circuit design, simulation etc.

Ultimately, I got so obsessed with it I got burned out and had to take a break for a bit but came back fresh and finished it. Did a few flights over the year with more and more interesting things culminating in a dual stage flight. I've still got the rocket ready to go anytime. Just gotta wait for the weather to clear up.

On the topic of rocket flight computers, here's a link to an FC I built last year for my model rocket. It does thrust vectoring and some rudimentary navigation. The control loops on this thing run at 200hz though. It's got a state machine for knowing what to do at each stage of flight as well.

This uses a simple PID controller to bring the rocket to any angle you want from an initial angle. There's a lot of settings that can be changed and variables to play around with. Right now, It's configured to do sort of what starlink does during it's flip maneuver.

Anyways just thought I'd share!
