Europe Finds LightSquared Harm to Galileo Signal
http://www.gpsworld.com/gnss-system/news/europe-finds-lightsquared-harm-galileo-signal-11902
"Analysis carried out in Europe, including by our own technical partner
the European Space Agency, has shown that transmissions from
LightSquared base-stations do indeed have considerable potential to
cause harmful interference to Galileo receivers operating in the United
States. Interference effects have been determined to occur in the range
100m to almost 1000km, depending on the type of receiver being used.
This obviously presents a grave threat to the viability of providing a
Galileo service covering US territory - a service which many studies
have shown will not only benefit Galileo users, but those of GPS too as
the two systems will be interoperable through a common signal design
providing significantly improved coverage and accuracy in urban
environments. The European Commission is also concerned about potential
impacts to safety critical aviation applications. Europe is covered by
the EGNOS system, which is equivalent and interoperable with the US
WAAS, and so it is vital that EGNOS/WAAS receivers fitted to aircraft
entering US airspace do not suffer degradation to the availability and
reception of their navigation signals".

At last: the word venality has been mentioned!
I have been thinking this over myself for weeks now and the only logical
conclusion is that someone at the FCC is going to receive a very large sum
of money from Harbinger/LightSquared for protecting/pushing/promoting this
insane project.
The more I read about it the more obvious it is.
