Interesting.
A personal observation:
A current ESA Education project. - ESEO plans to use 1263.5 MHz as an uplink to a L/V FM transponder. 2m / 70cm and S band were not possible as they are in use elsewhere on the same satellite.
The possible impact on Galileo was discussed / analysed for that frequency and no objections were raised.
ESEO, with contributions from AMSAT-UK is progressing from critical design review to engineering and flight model production.
I know amateur radio interests are represented at international meetings and negotiating spectrum is a difficult task, but the reality probably is that unless we have some more success in allocating some 'dedicated' spectrum for amateur radio satellites, then the chaotic trend for individual nations to allocate experimental licences in interference free zones will continue. ( ISS on 2395 etc)

I'm sure Michael will be expanding on this in a few weeks time at the IARU Conference.
Peter G3LTF set out the possible impact of Galileo back in his 2006 paper at http://www.southgatearc.org/articles/galileo.htm
From the paper it looks like a 700 Watt ERP amateur station could "knock-out" a users Galileo receiver at a distance of 18 km.
A number of radar systems have been forced to vacate the Galileo 1260-1300 MHz E6 transponder downlink which means there is more intensive use of other parts of the spectrum.
If the Amateur Satellite Service is to stand even the slimmest chance of gaining additional spectrum in 1200-3500 MHz at ITU WRC-18 then it would first need to be added as an agenda item at next years WRC-15 conference and that will not be easy.
