    [ . . . ] No need to observe the satellites you're jamming.

Yes.  I was careless with my phrasing.  What I meant was, "the
satellites that you care to impersonate, which are presumably the ones
that the victim can see."  Of course, you might as well just jam 'em
-all-, even ones below the horizon; it's not any harder...
