Sat-nav ‘jammer’ ...
Saw this when I thumbed through Autoexpress today. Online at Sat Nav jammer | Auto Express News | News | Auto Express
"It emits a frequency that blocks the signal from global positioning satellites. As a result, the black box can’t record movement data. The jammer unit also has a mobile phone blocker to stop the black box sending information back to its base. Essentially, it has the same effect as leaving a vehicle in a lock-up or underground car park".
What's the betting the gov. goes ahead with road pricing via GPS and just makes these 'illegal'. Which means that the only people who'll be using them will be the crims ...... anyone taking bets with me??
Dave
PS: I could definitely see a use for one of these!

Not saying I agree with road pricing..
but what your saying is that indiscriminately jamming GPS and GSM signals just to save you a few pence per mile is okay?
As for only criminals using them, these things would stick out like a sore thumb to anyone with some pretty simple bits of equipment - it would be like having a giant beacon with "I AM A ******" in flashing neon over your car.

But as long as they intend to introduce measures like road pricing then the crims will find ways around it.

Wide band jamming is well monitored and if you start playing with a jammer you are risking a lot of trouble. To start with anyone playing with this kind of kit anywhere near a military installation is risking the men in suits paying a visit..
Next on the hit list will be OFCOM, they will be looking for you too.

My argument isn't for or against Road Pricing. My argument is against wreckless and irresponsible illegal transmissions.
There is are very good reasons why such things are illegal. Do you have tracker fitted to your vehicle? Do you think that such a jammer would only jam the GSM in the black box and leave the good sim in your tracker, or for that matter, your normal mobile phone, alone?
Do you think the GPS jamming would only effect the black box and leave your tomtom working away happily?
Do you think such a device is likely to only effect the immediate confines of your vehicle, and not knock out everyone elses GSM and GPS for an unknown distance, probably into 10's of metres, possibly into 100's? Including those of the Emergency Services, Doctors, Fireman, Lifeboatmen, Vets.. ect ect ect who rely on these services?
Of course, electronic jamming seems a little pointless when you could simply place a lead box around the device to passively prevent the reception of signals..

In addition I am really surprised that in combination with internal guidance info and regular non jammed updates, the missile should have been able to discard any spurious info.
It would be interesting to know more about how those Russians devices had some effect.
