The U.S. military has a lot of informative publications such as this. They’re usually pretty easy to read once you find the relevant section. Those interested in this one might also like Naval Telecommunications Procedures [1]. It has a lot of administrative and Navy-specific information, but chapter 5 covers radio communication, including satellite communication (unclassified of course).
Edit: The Naval Electricity and Electronics Training Series (NEETS) [2] is good as well.
On a related note, the Federation of American Scientists maintains a really fascinating archive of unclassified military documents, which includes a lot of this kind of stuff (plus all sorts of other interesting documents). I think their archive tends towards slightly newer documents though. Or maybe I just haven't skimmed it thoroughly enough.
