With the widespread application of the Global Positioning System (GPS), people are increasingly dependent on GPS signals. However, in some specific situations, we need to shield or interfere with GPS signals to ensure safety or achieve certain special purposes.
Basic principles of GPS signal jammer
The working principle of the GPS signal jammer is mainly to cover or drown the original signal of the GPS satellite by emitting interference signals, so that the GPS receiver cannot receive and analyze the satellite signal normally, thus achieving the purpose of shielding the GPS signal.
The composition and work flow of GPS signal jammer
- The GPS signal jammer is mainly composed of two parts: a signal transmitter and a controller. The controller is responsible for controlling parameters such as the switch of the signal transmitter and the transmission frequency, while the signal transmitter is responsible for emitting interference signals.
- When the GPS signal jammer is turned on, it will emit interference signals at the same frequency as the GPS satellite signals to the surrounding space. These interference signals will cover all GPS satellite signals in a specific area, making it impossible for GPS receivers in this area to receive and analyze satellite signals normally.
- GPS signal jammers usually use wide-band interference technology, which can cover the entire GPS frequency band, making all GPS satellite signals in this frequency band unable to be received normally. At the same time, the strength of the interference signal can be adjusted as needed to achieve the required shielding effect.
