GPS jammer can effectively cut off GPS signals
About half a century ago, the US Department of Defense began an experimental project to launch a series of satellites into space in order to locate any location on the earth. 47 years later, from activity tracking apps on our smartphones to navigation systems on airplanes, the ubiquitous global positioning system is known as the acronym GPS. Before GPS chief architect Bradford Parkinson won the £1 million Queen Elizabeth Engineering Award last week, he told ZDNet that making the tool accessible to everyone was his plan from the beginning of the project.
In 1983, under the impetus of the space race and in the context of the Cold War, the Reagan administration announced that it still wanted to provide civilians, but first assure the military with GPS. Bradford Parkinson recalled: "For President Reagan, the reliable knowledge was the ability of the government to provide beacons for ships or navigation lights for aircraft." "We are here: Now the world is using GPS. Take it for granted",
What Ronald Reagan could not predict at the time was that engineers would develop cheap and complex chips that could power more than 5 billion smartphones around the world, all of which are equipped with GPS and help global technology. According to its creator, GPS today still faces the biggest threat: gps jammer. As a reminder, when a third party broadcasts too much noise on the same frequency as a satellite to send data to a terrestrial receiver, it will suffer interference, which in turn calculates their location by determining their distance from the satellite. .
By sending radio signals on these frequencies or frequencies used by proximity technology, GPS jammers can effectively stop GPS navigation. Bradford Parkinson warned: "We must protect these frequencies." "Billions of people in the world rely on GPS systems. If our GPS does not work, I think many of us are not good at reading. map."
The Federal Communications Commission (FCC) (equivalent to Arcep) is very clear in the United States. Therefore, the agency has taken measures to punish the use of GPS jammers, which are small devices that emit radio signals of the same frequency as GPS to cancel or distort satellite signals. The chief architect of GPS said: "The most serious threat is when your national authority allows ground transmitters to work near GPS frequencies. I have solved this problem for nine years."
