“Our employees complain that prisoners have phones and contact people outside the prison, but the Government Press employees spend their working hours at the department as prisoners, unable to call their family members even during the lunch hour,” she said. She said the prisons authorities should crack down on the use of mobile phones inside the prisons instead of installing cell phone jammer which affected areas residents, nearby government departments and even who are passing by the prisons.
While jamming isn’t anywhere near shooting, the provocative activity “could lead to an escalatory pattern that could be negative for both sides,” and the US will “not look kindly” on the practice, according to an expert.
GPS signal jammer can be bought on the internet and range in size from that of a small cigarette lighter to a suitcase, with a range of a couple of metres to a couple of hundred. You can buy combination jammers that also block mobile phones, all for a few hundred dollars. Customers for these devices are drivers seeking to shut off their employer’s GPS tracker from their vehicle, car thieves and other criminals.
Jamming, which means blocking or scrambling a drone’s reception of a signal from a GPS satellite, can be uncomplicated, according to Dr. Todd Humphreys, the director of the Radionavigation Laboratory at the University of Texas at Austin.
Military wants to prevent the FAA from decommissioning radio NavAids and secondary radar. The FAA had counted on $100 billion from the decommissioning after the introduction of ADS-B. Jamming GPS signals forces aircraft to rely on the old systems, so it has become part of a politics game.
While Lamrani said that jamming “can be dangerous” if it targets navigation or communication systems, the US Navy’s electronic attack aircraft can likely more than handle the challenge.
But while manned aircraft can usually fight back against signal jamming, and pilots in a cockpit can always use their own judgment if communications or navigation is lost, jamming could pose a serious threat to the US Navy’s drones, as there’s no one in the cockpit, according to Lamrani.
