Stupid Attorney taling about GPS's

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?

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."

GPS is a spread spectrum hahn waveform and has good resistance to
interference.

I could not make that same specific claim for the data link used by police.

Well, I will, in any case. Jamming a signal blocks it in such a way that it is
pretty much useless. Jam the GPS signals, and your receiver can't tell where it
is. Spoofing signals causes the receiver to report an incorrect location while
"thinking" that everything's working correctly.
