[Dune] What was actually stopping the Atreidies from launching their own monitoring satellites.

The Spacing Guild had absolute control over what could and could not be placed into space. Anyone attempting to put satellites into place without Spacing Guild Permission would find themselves on the wrong side of the Guild and that would result in being a very very dead house with absolutely no way to run away.
