The Risks of GPS Jammers

A little over 10 years ago I sold a Fleet Management and GPS system to a company wanting to track and optimise around 600 vehicles.

Within a couple of weeks of the first installations, I started getting calls from their management saying that several of the vehicles could not be tracked.

I thought this was odd and contacted the auto electrical company that was doing the installations for us. They had no ideas as to why that was happening and invited me over to inspect their work, which I did. Their work was perfect.

It kept happening and I was starting to get a picture. I arranged for a vehicle that had gone off the radar to be directed straight to the auto electrician without deviation. He was sent off to the smoko room and they went under the dashboard of the van he was driving.

They found the GPS antenna wrapped in aluminium foil. It turned out that the technician in the smoko room had been ‘tea-leafing’. If you don’t know the term, tealeaf is Cockney rhyming slang for thief, in this case a time thief.

Word had got out that if you put foil around the aerial, the system would appear to be working, but they would have no idea where you were and the signal would be the same as if your vehicle was in an underground carpark, which sometimes it might legitimately be.

Anyway, the message went out that this was to stop, and those who had a lifestyle based around doing lots of things other than work in company time, might like to find a different employer.

Today there are new ways of blocking GPS signals. They are illegal and potentially dangerous as outlined in the video above.

Having had my home ‘cased’ by would be robbers, I could have been tempted to buy a GPS signal jammer and block their drone’s travel. I chose instead to report them to Civil Aviation as I knew where they lived, and had observed them scaring people in bus stops and on the street. I also heard from neighbours that I wasn’t the only one wanting them to cease and desist. I briefly considered the merits of a slingshot, after all the drone kept flying over my property, with the ‘pilot’ no doubt watching me on his laptop. I would have been quite happy for them to come and pick up the pieces. Of course I wouldn’t actually do that, but I enjoyed the mental image.

tempted to employ a slingshot and spoke to the Police about it.

There are more and more people flying drones flying around today, and many drone pilots don’t know the law. There was a news story last week about this problem. Basically you can buy them online or from hobby shops and even some of the ‘toy’ drones are big machines.

Anyway, the key takeout is GPS jammers are not only illegal to use, they can also cause danger.
