Aiming to curb situations in which civilian vehicles are stuck “off the grid,” a Caesarea- based firm has begun shipments of a system that prevents disruptions to GPS.

The cybersecurity company GPSdome Ltd. is marketing a miniature “GPS anti-jammer,” a pocket-sized gadget that protects GPSbased systems from disturbances at a more affordable cost than comparable military appliances, according to the firm. The product works to counteract the effects of jamming devices – radio frequency transmitters that deliberately block communications like GPS.

I only discovered GPS repeaters a few months ago - My local fire station has one outside with a little aerial and it retransmits the satellite data inside so the fire engine sat nags have continuous signal ready to turn right or left and not have to wait for lock up outside in the clear.

I cannot for one minute fathom how these can work?

I mean. Its not like they can transmit on the frequency to jam the jammers as this would surely cause more of a jamming effect?
