Re: What's the point of this?
it seems highly unlikely that the USA would ever deprive the rest of the world access to the civil GPS service
How could they do that, without making all GNSS receivers (including US ones) useless? For that matter, how could the EU allow widespread use of Galileo, except to Brits?
Military-precision controls I can see, but the civililian service is surely beyond that level of control now.
