Do different GPS companies have different satellites that their customers beam to?

On a related note, how many devices can communicate with a satellite before overloading it?

Most of your question has been answered but here is another part that wasn't. All GPS satellites are owned and operated by the US Air Force. They maintain these systems and provide their signal for free use to anyone in the world who wants to "listen". A big radio station in the sky, all you need to do is tune in to hear it.
