Are GPS jammers safe to use?

Nowadays, technology is becoming more and more developed, so GPS signals are becoming more and more accurate. Sometimes GPS signals can facilitate people’s lives, such as maps that can use navigation functions, but sometimes GPS can also bring bad things, such as In some special industries, there are also people with evil intentions.

1. Whether in movies or in reality, there are scenes where criminals install GPS jammers to make a vehicle equipped with an advanced positioning device "disappear" out of thin air.

2. Working principle of GPS jammer. Because the GPS signal of the locator is the same as the mobile phone signal, it is easily interfered by electronic devices. Therefore, by releasing radio interference waves, the device can disable the GPS locator within the specified electromagnetic band, creating the same electromagnetic environment as the device. The purpose of blocking signals. At present, the main thing is to block the GPS satellite signal so that the data cannot be uploaded to the platform, so that the device cannot be used offline normally.

3. Scope of use. It is reported that unauthorized installation of relatively high-power GPS jammers has a wide interference area and can simultaneously block 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 make calls and surf the Internet. In addition, China's Beidou signal affects the GPS signal, which is relatively weak, making it impossible to navigate and position the area. Once a signal blocker like this is turned on, it will seriously disrupt communications and form a communication blind spot. Therefore, the GPS signal jammer must have its own principles and cannot interfere with other people's signal use during use.

Some people will work with relatively small jammers, but with the upgrading of GPS locator equipment, small-power jammers cannot achieve the shielding effect. So if you need good shielding effect, you need a good shielding instrument.
