Are GPS Jammers a thing? A multipart question.

Cell phone jammers are not uncommon at all.  I think some were marketed to parents to put in their children's cars, wired to the ignition so they wouldn't talk/text and drive.  If these things are cell based, that's probably what they are using. 

In reply to Dr. Hess :

Agree, they would have a hard time jamming the signal to the GPS receiver.  But jamming the way (probably cellular) that info is transmitted back to the dispatcher is easier.

Hey Wally. If you need a distraction, tell us if anything ever happened with this mystery...

Canoe warning.  Post like a real person or get sunk.

I missed this. We never solved the mystery as to what was happening, but it happens less often as the system has been upgraded, fewer components are accessible, and almost all of the buses have onboard cameras

I remember this one. I've been wondering all this time! and didn't know it  😂

I wish we had come up with some sort of explanation. My assumption is that someone figured out how to disable the system, and was very careful who they let know so we never figured out what was being done.
