I went deep into this earlier in the year, here are a few resources I found helpful:

- https://www.ariss.org/uploads/1/9/6/8/19681527/k9jkm_2012_sy... has a good overview of how to hit the ISS (and other sats)

- https://www.va3hdl.com/projects/gpredict-and-hamlib is the software stack you probably want to play with
