guys,
I wouldn't treat this article seriously from the technical POV,
the passage:
"This can be compared to a radio-station signal: When the frequency is tuned in precisely a clear signal is received from the radio, but when a slight turn from this frequency occurs, the signal weakens and static or other radio stations can be heard. At times even when the precise frequency is tuned in noise from a nearby radio frequency can bleed in. "
is very stupid to be considered as a meaningfull one.
When I was reading it, I felt like the author was writing for "dummies" or managers and barely knows the subject
. Too few technical details. even such important params, like modulation or transmitters' power, are given.
As I remember from my study, the whole (reasonable) frequency spectrum from Hz to GHz is divided and each band is already assigned to a certain country or service. there's a special international organisation (ISO? IEE? not sure about the name) which rules this stuff.
So, the problem is clear: if US's GPS deviates outside it's dedicated frequency band, it must be fixed and it's the problem solely of the USA. If EU or anybody else want to use it's part of spectrum, it MUST be free of anybody else's signals.
about the politics...
I think, that the EU is a new growing superpower, comparable to USA or former USSR.
So, it has to posses it's own systems, like military force, information network etc.
