Nowadays, technology is becoming more and more advanced, so GPS signals are becoming more and more accurate. Sometimes GPS signals can facilitate people’s lives. For example, maps can use navigation functions, but sometimes GPS can also bring bad things, such as In some special industries, there are also people who plot badly.

1. Case. Whether in the movie or in reality, there are scenes where criminals installed gps jammer to make a vehicle equipped with advanced positioning devices "disappear" out of thin air.

2. The working principle of GPS jammer. Because the GPS signal of the locator is the same as the signal of a mobile phone, it is easily interfered by electronic devices. Therefore, the device can make the GPS locator invalid within the specified electromagnetic band by releasing radio interference waves, forming the same electromagnetic environment as the device. The purpose of blocking the signal. At present, it is mainly to shield GPS satellite signals so that data cannot be uploaded to the platform, so that the device cannot be used normally when offline.

3. The scope of use. It is reported that the unauthorized installation of GPS jammers with relatively large power has a wide interference area and can simultaneously shield the 2G, 3G and 4G networks of the three major operators. Communication base stations within a diameter of 2 kilometers will be interfered, causing users to call and surf the Internet. Affected; in addition, for the GPS signal, which is relatively weak, the Beidou signal of China has an impact, making it impossible to navigate and locate the area. Once a jammer like this is turned on, it will seriously disrupt communication and form a communication blind zone. Therefore, GPS signal jammers must have their own principles, and they must not interfere with other people's signals during use.

Some people will work through relatively small jammers, but with the upgrading of gps locator equipment, jammers with low power cannot achieve the shielding effect. So if you need a good shielding effect, you need a good jammer.
