Trevor: You call it "the other issue" but it is the only issue. They do not give a tinker's damn if they interfere with us (and I suspect they won't) but the ability to sell receivers with CRAP for front ends (in terms of dynamic range, IMD, etc.) making it cheaper to manufacture is severely hampered by the "licensed stations" in adjacent bands. There will be regulatory relief sought for the "health and safety" etc. services provided by Galileo from those stinking pest hams who are simply obeying the law on their licensed systems.
I am still of the opinion that this system serves no useful purpose whatsoever except to say "us too". It is a political impossibility to turn on SA now in my opinion but now there will be no need to at all. I suspect a treaty guaranteeing no SA and no allowance for design and sale of jamming equipment would be a LOT cheaper than this system.
