No, but I am sure you will enlighten us. I have a fairly good idea, but I
am not sure what those specific terms mean in the world of GPS. By the way,
I did not use those terms - you did. I used the broader term:
"interference."

Huh,

I was under the impression that the GPS signals are fairly weak and
intentional interference is a serious issue.
Is that not correct?

Intentional jamming of GPS is difficult for newer units, as a simple
filter
algorithm will remove most jamming signals. Do you know the difference
between spoofing and jamming?
