GLONASS GPS L1 1570-1580 MHz vehicle mounted GPS Signal Jammer, portable Signal Jammer
Description of portable Signal Jammer:
GPS jammers come in a variety of designs, each suitable for a slightly different purpose. The first and most popular model to enter the mainstream market is one with a cigarette lighter, which effectively interferes with signals with a radius of 1-10 meters. It's not enough to interfere with the signals of other vehicles, but enough to make you fall into the silence of GPS interference. However, other versions of battery powered and effective for different distances are also available.
Why do you need a GPS jammer?

For some people, it may be a bit confusing why someone wants to interfere with GPS signals. However, some people have special privacy needs, such as massaging their paranoia, preventing law enforcement officers from tracking unlicensed cars, taking an unauthorized lunch break with a company car equipped with GPS, or a teenager who doesn't want their parents to track their GPS phones. Whether all this is legal or not is entirely another question.
How does vehicle GPS jammer work?
The basic purpose of GPS signal jammer is to prevent GPS recorder from receiving satellite signals or sending them back to its base station. Now, it's possible that any GPS you've ever come into contact with will use a radio frequency other than civilian: military units use a very different frequency.

The working principle of GPS signal jammer is to send its own signal at the same frequency as GPS device. This kind of noisy signal prevents it from receiving or sending any useful information. It can send many kinds of noise signals; Some call for narrowband Gaussian signals, others call for a simple continuous wave.
GPS signals are very weak, and they are distributed on the earth surface by high orbit satellites, so they are the most easily interfered signals.
This is a mini portable GPS vehicle jammer, through programming hidden GPS location, protect your privacy information, ensure your personal safety. It is a high-tech product that can block the GPS L1 frequency range of 1570-1580 MHz in the range of 1-10 meters (radius). The device has only one antenna. If you want to shield GSM, WCDMA and DCS signals, you can customize it, but only one frequency range can be accepted.
GPS jammer for special purpose vehicle. We've designed this small but convenient device to help millions of truck drivers around the world, because their employers have installed GPS tracking systems on their 18 wheelers, and they think their privacy rights have been violated.
Of course, the gw-jm1 tracking jammer is designed to help all these guys regain their privacy once and for all. But they're not the only people on the planet who drive cars, are they?
