GPS, GSM Cellphone Jammers Hit Mainstream, Calamity Ensues November 18, 2006

Don't get too reliant on that GPS receiver, Magellan, since companies are now starting to release devices that locally block GPS signals. Detectnu's device not only block GPS signals within a 50-meter (164-foot) radius, but also GSM cellphone signals in a 20-meter (65-foot) radius. Another such device—the RJ-G1575 GPS jammer from Radixon Hadrian—blocks GPS signals in a 50-kilometer (31-mile) radius. Now, I can completely understand cellphone jammers (hint: people have no concept of tact in New York City and love to yap about God knows what quite loudly), but blocking GPS? What good does that do, other than give mischief makers a rise?
Ok, so Radixon Hadarian claims that the device can be used to thwart GPS-aided terrorist attacks. Yes, and I'm Jack Bauer. Let's leave the crime fighting to the professionals and not to gadget geeks.

These might be useful for the GPS aided road pricing they're talking about introducing in the UK where a GPS receiver tracks your cars movements and charges you for the journeys you make. If the tracking device can't receive GPS then there should be no charge.... maybe?
If this device works as promised, it can also be a powerful weapon for individuals to protect themselves against state-sponsored crime - also the kind coming under a ‘legal’ cover (paragraphs). How often do you think the police & co use these weapons without being allowed to use them, just because they can feel safe that nobody will realize it and they get away with it.
An alternative to this device could be a receiver that protocols close-range GSM traffic of all kinds. Thereby it ought to capture the traffic generated by ‘your’ bug. And by the way, according to recent spiegel.de reports (there had been such rumours for a long time already), this bug can be your own switched-off GSM phone, because these apllicances can be remotely switched on without you realizing it. From that moment on, ‘they’ can not only follow your moves; they can also listen in through the microphone, and irrespective of phone calls.
our gsm/cdma/pcs/dcs/gps jammer could block all gps tracking devices and navigation system.
