That was a very technical-sounding discussion, but you lack a certain basic understanding of how the Apollo spacecraft navigated.

For instance, in space, you cannot get a 3D position fix from the stars. You can only get your orientation.

You discuss the shortfalls of the Apollo navigation computer, but fail to realize that the “Apollo Primary Guidance, Navigation and Control System (PGNCS)” was not actually the primary means of navigation. The data gathered from the earth-based tracking network and processed by earth-based computers was much more accurate than the onboard system.

And so on…

But thanks for prompting me to look into it more. I had some questions about how space navigation was done but never looked into it before.
