you may find it tiring, but feel free to present some facts
backing up your apparent belief that GPS is immune to jamming.

People here never seem to get tired of misrepresenting and distorting
my position on this (apparently it is too difficult to argue on a
factual basis).

I never claimed that GPS was immune to jamming. I have stated, and I stand
by it, that it is pointless to argue about GPS jamming if the other,
existing services can also be jammed.

But since nobody here has ever produced proof of either, this argument
is pointless, and I don't feel the need to start yet another mudslinging
contest yet again.

In the Iraq war, a GPS jammer was taken out with a GPS guided missile.
That speaks worlds about the GPS jamming issue.
