Triangulation is damn easy. If the US can put on bomb on a suspect satellite phone user back in the 2000's (and they did!), they can certainly send a bomb on that today.
Sat phones during the second gulf war (maybe even the first) became a liability. The transmission lit them up like a god damn beacon saying, "Bomb goes here!".
Good luck if your mesh network is on 2.4/5/6ghz.
It'll blend in with background radiation from home routers.
Triangulation, the math isn't the hard part. Where exactly on the continental United States are you proposing dropping ordinance? MOVE in 1985 was controversial even back then.
