Textbook? I think SpaceX wrote a new textbook and continue to improve it.
By the way, if I ever get ambitious, I’m going to figure out MOA for SpaceX landings.
Landing a rocket inside a 50′ circle from 100 miles up is probably pretty fine shooting. (WAG on the size of the circle, by the way)
[pedantry]
Pretty sure MOA only applies to small-arms ballistics.
Dunno what measure they use for guided/controlled landings, but CEP (circular error probable, 50%) was used for guided missiles & bombs.
Having an MS in satellite guidance & control, I’d love to get a geek-level briefing on the algorithm and equations of motion they use.
Trouble is, last one of those I sat in on was about four decades ago; and it was a bit over my head, even then.
Might look like magic, now

Believe it or not, CEP has crept into small arms shooting.
I wonder if CEP would be a good way to describe the inevitable “flier” one gets when target shooting? (based on my very hazy understanding of CEP)
Don’t see why not.
CEP is the size of a circle that includes 50% of the shots closest to the bullseye measured from the bullseye’s center.
It’s not the same as group-size, which doesn’t consider the bullseye’s location

Thanks,
would’a been a real shame to lose it due to a screw-up
Obviously, the OS wasn’t designed by MS, else they’d be sending a version of, “Have you tried rebooting the computer” to Voyager on a regular basis.
