The field strength of the jammer and the type of the jamming wave are important

　　GPS Jammers and Jammers - Still Using Smart Hardware Location A GPS jammers is a device used to jam or completely block Global Positioning System (GPS) signals operated by the U.S. Department of Defense. Such transmitters have difficulty receiving radio signals correctly. For this purpose, electromagnetic waves are emitted that completely or partially superimpose the signals and waves of the disturbed transmitter, rendering them unusable. Jammers can operate on the same or adjacent frequencies, the field strength of the jammer and the type of jamming wave are important.

　　GPS jamming requires very little jamming energy to temporarily or completely block the GPS signal. Because GPS satellites orbiting more than 20,000 kilometers above the Earth's surface have relatively low transmit power. Even small GPS jammers can jam signals within a radius of about 10 meters. This means that it is no longer possible to GPS track the vehicle with a GPS tracker.

　　Mobile Smart Positioning Devices Offer Special Protection Against GPS Interference Mobile Smart GPS Tracking Transmitters provide the option to continue locating the vehicle in the event of GPS interference. The tracker supports so-called cell positioning (also known as GSM positioning or cell phone positioning) as an alternative.

　　Such cell phone blocker are used time and time again in criminal cases. The perpetrator tries, for example, B. to overcome the anti-theft system in the case of shoplifting. Car locks are also increasingly being manipulated by jammers to open vehicles and steal items from them. If the entire vehicle is stolen, thieves use GPS jammers to block GPS signals over a wide area. Tracking systems used for vehicle tracking usually show the fleet operator the location of his truck or car at any time, so they cannot be used.

　　Protecting Against GPS Jammers and Jammers In areas of particular security relevance, the use of sophisticated technology can reduce the effectiveness of GPS jammers. For example, in aviation or the military, special antennas are used that only receive signals from a certain direction. However, this technology is rather impractical for companies in the logistics and transportation, trade, construction or service industries who want to use GPS tracking to monitor cars, trucks or construction machinery in their fleets.

　　In this regard, there is always a residual risk that GPS positioning will be corrupted by criminal energy to disable anti-theft protection or use the vehicle for unintended purposes. However, it should also be noted that the use of GPS jammers can result in serious criminal penalties. Because buying GPS jammers and using them is not only prohibited, but can also be very dangerous, as radiation can also damage sensitive instruments (such as in ambulance or traffic control systems). may interfere. Statistics from the Criminal Police also prove that locating vehicles or trucks using GPS trackers installed in vehicles is an effective method of locating stolen vehicles, even if they have been taken abroad.

　　While GPS jammers are banned, fleet operators should protect themselves. Certain gangs specifically target valuable machines and trucks.
