That is not he fault of the GPS.

No, but it's a human mistake. It's a training issue to make sure that
when the GPS bings off a waypoint, you check a few landmarks to make
sure you're where the gadget says you should be. Currently, that doesn't
reliably happen because people have too much faith in the GPS.

the GPS acts up or the information it provides isn't used wisely.

That goes for anything and everything. Not just GPS.

Training is very important. To quote a friend, "You have to be smarter
than what you're working on."


The trouble is, GPS is too damn useful. Mike Marron wrote eloquently
about how a working GPS can replace most of your flight instruments...
as long as the GPS is working. But it's a low-powered signal from orbit
and it's easily jammed. GPS jamming isn't a feature of civilian life,
but it's a serious military problem. GPS offers much more than any other
navaid I've heard of, no wonder people turn to it first.

Oh Bo....ks.
GPS is easy to TRY to jam. Well known signal processing techniques are
all that's required to defeat jamming.
