minute part of it's orbit, I would think that the conclusions drawn would still be valid. It's an interesting read: http://www.microwavers.org/papers/iaru/C5-13_Galileo.pdf
For me the key point is that Peter estimated that a single Amateur Radio beacon operating at 1296 MHz such as that at Martlesham could force every Galileo receiver out of lock over a radius of 16 km (10 miles).
It's not just the increase in noise floor that needs to be considered, it's the concern that a typical Amateur station will jam Galileo receivers over a wide area. If at some point in the future that transponder were used for what might be losely interpreted as "safety critical" applications then would forsee Amateur Radio activities either being suspended or power levels being severely curtailed in 1260-1300 MHz.
Now it's going to be 2012 before they get the Galileo system fully operational so we should at least get 4 years use out of the P3E "L" uplink. What happens post 2012 is a big unknown.
