Lady turned on to the tracks in Mineola NY, on the LIRR main line. She was following her GPS and it told her to turn.

Fortunately she got out before the train hit the car.

We were in the restaurant in the story when it happened.

GPS signal is a weak one.  It can be compromised easily, it seems.  A trucker in the New York area wanted to block the signal his bosses were receiving, so that he could go where he wanted, without them knowing.  Whatever he did to his GPS wrecked havoc with everyone's system for a few miles around.  A story I learned a couple of years ago.

Sounds like a jammer.

Well, how many people have hit the 11'8 bridge with drivers in box trucks following the GPS receiver.

There's a 10' 6" RR trestle near my job. Gets hit once a week minimum. Most times its a box truck opened up like a can of sardines. The worst I saw was a brand new CAT Excavator with the entire cab ripped off and laying on the ground. The machine didn't have a scratch on it...until they hit the bridge of course.

Cell phones (don't know about GPS navigation devices) only use GPS satellite signals for location services as a last resort.  Instead, they augment using a combination of technologies, including distance and direction from cell towers and strength and direction of signal from wifi access points (which are mapped by services like Google cars/maps).  If a cell phone has to resort to the GPS signal, it can take up to 10 minutes to find it's location.  I would think most modern dedicated navigation devices do similar things.

 

 

"She was following her GPS and it told her to turn."

I love the saying, "you can't fix stupid". The first stupid thing was not being aware of her surroundings. You see it all the time, not only with cars but with pedestrians in NYC on their cell phones. Walking into other people AND traffic. The second stupid thing is the blame game. A good part of that lies on the legal system and settling cases because its less expensive than going to Court. Personal responsibility (Harry truman , "The Buck Stops Here") is as anachronistic as what we were taught in school about George Washington who supposedly said, "I cannot tell a lie". There are undoubtedly more stupid things here, but why bother.

There are a number of locations in my area where software like Google Maps and Waze are a little off in pinpointing locations. It's been a while since I've used my Garmin, but as I recall, it had the same errors.

Cell phones (don't know about GPS navigation devices) only use GPS satellite signals for location services as a last resort.

The cell phone I am currently using allows the user to turn the GPS off and on. I have Google Maps and Waze. Both want the GPS turned on. Google Maps will run without GPS, but it is more accurate with it on.
