  Any conductive metal will reflect and absorb incoming and outgoing signals from the equipment and interfere with its operation.Similarly, Wi Fi networks operating in the 2.4 GHz or 5 GHz band will also interfere with GPS signals in the L1 and L2 bands.The GPS signal will also be interfered by other radio signals operating in the same or near frequency band.The reception of reflected signals may also cause the receiver to lose track of the satellite it should track.Places with high-power transmitters, such as radio or television broadcasting stations, may hinder the normal operation of GPS.

  These externally transmitted signals will interfere with the GPS signal and cause reception interruption, resulting in the GPS receiver being unable or inaccurate in calculating the position and time.This can lead to signal interference and distortion, as well as delayed signal arrival.The best way for navigators to avoid this situation is to fully understand their route or location and whether there are electronic equipment or transmission equipment that may cause interference in the area.It happens where there are many transmission devices that broadcast using different signals.

  This is a common problem in passenger cars, because passengers usually do not understand the system before boarding.GPS interference may also come from equipment that is not in the vehicle specific radio spectrum but is close enough to block the frequency of the signal.This is why passengers are required to turn off their mobile phones or other gadgets before takeoff or landing.The simplest way to avoid interference in the same radio band is to advise the crew and passengers to limit or stop using equipment that may interfere with the vehicle's GPS at the critical moment of the journey.

  Multipath is a phenomenon that occurs when GPS signals bounce off reflective surfaces (such as buildings, trees, etc.) before reaching the receiver.Any vehicle traveling long distance by land, sea or air is usually equipped with global positioning system (GPS) technology to help it navigate.Shipping and transportation companies, material handling companies and high-end tourism suppliers rely on GPS to deliver their products or passengers safely to their destinations.It makes GPS network indispensable today.Since GPS operates on the radio spectrum, another device operating on the same range and radio frequency can be used to interfere with the signal.

  For example, mobile phones operating in the 850 MHz or 1.9 GHz band may interfere with the navigation signal in the L1 band (1575.42 MHz).Wrapping the GPS tracker in aluminum foil is enough to do this - although copper and even silver can do it.This is a very cheap and simple GPS jamming method GPS jamming is a process that uses RF transmitting equipment to deliberately block or interfere with GPS signals used for positioning, navigation and time service.These RF transmitting devices, called GPS jammers, are relatively small and simple transmitting devices that can transmit RF signals of the same frequency as GPS signals.
