A GPS interference is very easy to establish. GPS signals are relatively weak and centered on the 1.0, 1.2, and 1.5 GHz frequencies in the microwave spectrum. Simply transmitting microwave energy near the receiver will mask the weak signals emitted by the satellite (about 20 kilometers away) and disable the GPS device. Note that this does not fool the signal or cause the receiver to calculate and display incorrect positions, which can invalidate the receiver. Any properly designed GPS receiver will indicate failure because no satellites are present or RAIM errors are present, which is a self-diagnosis, indicating that the accuracy of GPS positioning solutions cannot be guaranteed.
You know, there are all kinds of FM modulators in the Chinese market, but some people who are not familiar with it don't even know what it is. FM modulator is a small tool, you must install it in the cigarette lighter slot, and then insert the USB key into it for normal use. This device will play the music recorded on this memory card and transmit it in the FM band frequency so that you can receive this music through the FM receiver. The device is designed for those who have a car that is not compatible with USB.
Most of these devices use the frequency of 86.6-96 MHz and cannot physically block the gps jammer system because their signals are at the frequencies of 1227.6 and 1575.42 MHz. Therefore, please use a state where the operating frequency bands are completely different and far from each other, so that perfectjammer.com can claim that there will be no real interference between them. The GPS-blocking signals are located at 1227.6 and 1575.42 MHz. If you need to stop GPS, it is best to use some of our GPS jammers, especially this one! So you can bet with the people who tell you, all you have to do is send them a link to the question.
This product is suitable for classrooms, conference rooms, libraries, cinemas, etc. Some educational institutions also buy the product. It is one of the most popular desktop interference devices currently. If you have higher requirements for interference performance, this device is your best choice.
