Seems Galileo has four different services that it offers. Open Service is the public service. If you understand the protocol and radio signals, you can build your own device to read it yourself. High Accuracy Service used to be the commercial service, but is now just called HAS and is offered free of charge apparently. Then there is Public Regulated Service for government bodies, and a Search and Rescue Service.
