I use Qiling [0] (built on top of Unicorn) sometimes for this kind of things (it can take application snapshots, that you can restore; and you can also use something similar to x86/x86-64 memory hardware breakpoints too). Might fit what you want, although it can sometimes be in a pain in the rear to set up...

I'm really interested in knowing how they could get such a precise measurement (even accounting for errors), especially in the field (outdoor). There's no figure depicting the apparatus they used, I wonder how it looked like.
Sometimes, I just ponder at how ignorant I am. If I was tasked with the same assignment, I'd definitely fail and this was performed 250 ago!
In the search box, input "ISS" and filter by perigee (min: 380; max: 500). You should see the name of one of the modules of the ISS, such as "ISS (Zarya)" [0] or "ISS (Nauka)" [1]. If you can't find it on the visualisation at first, you can get its current location at https://isstracker.pl/en .
Would have been better to link to the repo [1] directly.
The repository contains the materials of a class, so without attending the class or having a rather strong pre-existing knowledge about hypervisors on x86-x64, the material is going to be very hard to follow.
From my PoV, there are definitely better (as in, explained with a lot more details) tutorials online on how to start your hypervisor from scratch which I'd recommend before trying to understand this one (which has some really nice peculiarities such as Fuzzing UEFI with code coverage).
