That would require you to be able to decrypt the encrypted signal that the satellite is broadcasting. Which you can't.
All these third party observers see is a bunch of digital noise continuously being broadcast by the satellites. They have no way of telling digital noise destined for a particular sub from the rest of the digital noise. So the signals convey no useful information to them.
