I never understood how this works, at least effectively. Isn’t this just a device DRM? If you can build an ICBM you can probably hack a gps receiver, or build an unlocked one, no?

And thus you could use existing gps infrastructure (ie avoid the expensive part of launching your own satellites). What am I missing?
