Tired of being watched for your whereabouts? Annoyed at being exposed to others all the time? Then you need a GPS jammer. The best way to protect yourself from unwanted location of other people is to have a GPS jammer device in your hand.
GPS signal jammer are portable devices that are literally gadgets that prevent GPS tracking devices from receiving signals without which they cannot acquire geographic locations. They transmit their own signals on the frequencies used by GPS tracking devices, which can mix or block other GPS signals.
There are a variety of GPS jammer on the market today. Among them, the mini carry-on is the hottest, as it is more bulky and easier to carry. In addition, most of us who use jammer prefer it to be shaded and unobtrusive, so portable can be the best choice.
Usually the price of GPS jammer can range from twenty dollars to more than one or two hundred dollars. This always depends on the mission of the jammer and its function. That is to say, the wider its working range, the higher the cost. Thus, when choosing a jammer gadget, make sure that it fits your needs and budget.
What is a GPS jammer?
GPS signal jammer are small, high-powered radio frequency (RF signal) transmitters that can disturb legitimate communication devices – cell phones, GPS.
What do GPS jammer look like?
Since the devices that can block GPS come from multiple manufacturers, they vary widely in shape, size and dimensions, making them difficult to spot inside a driver’s car. Most rarely, GPS blocker work in a small area, unplugging power sources such as cigarette lighters or iPhones and blocking the signal from GPS trackers installed in the vehicle’s cockpit.
How do GPS jammer work?
Car gps jammer work by generating a white noise radio signal that transmits at a frequency opposite to GPS satellites, which can block signals from GPS tracking devices and navigation systems.
GPS receivers rely on low-power microwave signals broadcast by GPS satellites. Signal jammer will operate with higher power but shorter range radio signals overwhelming these satellite signals to create “noise” that makes GPS tracking systems think that GPS signals are not available.
In some cases, a satellite failure or solar flare can temporarily terminate GPS signal transmission. the difference with a GPS jammer is that it retrieves radio signals or signal noise that is opposite to the frequency of the GPS device to mask or distort the GPS satellite signal. When this happens, the GPS device will no longer be able to calculate its position because the satellite signal is masked by the scrambling.
The GPS tracker receives microwave signals from an array of satellite transmitters orbiting the Earth. Once the tracker receives signals from four or more satellites, it goes through a series of time calculations and trilateral measurements to determine its position. The receiver relies on these accurate and specific satellite signals to determine its position in the world. the GPS tracking device then transmits this position and speed information to the monitoring position, usually over a cellular network.
Do GPS jammer work?
Yes gps tracker jammer or interceptors do work but have limited range and can be easily detected by modern trackers with anti-jamming technology, for example police forces can easily detect jammers using jamming detection scanners.
GPS jammer and jammer protection
In areas of particular relevance to security, the use of sophisticated technology can reduce the impact of GPS jammers. For example, in the aviation or military sector, special antennas are used that only accept signals from a certain direction. For the use of GPS tracking to track cars, trucks or construction machinery in the fleet of logistics and transport, trade, construction or service companies want to monitor, such technology is relatively inapplicable.
In this regard, there has been a certain residual risk that the GPS positioning will be destroyed by the risqué energy to disable anti-theft maintenance or use the vehicle for unintended purposes. However, it should also be noted that the use of GPS jammer can incur serious criminal penalties. Because the acquisition of GPS jammer and use them is not only stopped, but also can be very risky, because the radiation will also damage sensitive instruments can be disturbed.
Statistics from the criminal police also prove that the car or truck is located by the permanent installation of GPS trackers to stop the car is an effective way to locate stolen vehicles, even if they have been taken abroad.
Who uses GPS jammer?
GPS jammer for vehicles are used for a variety of reasons. GPS jammers were last manufactured by the government and are designed for military use. Concealing the status of the vehicle is critical to the success of the mission. These devices act like a cloak, providing the military with privacy, improved security and an overall advantage in high-risk situations.
In life, some speeding drivers can use scrambling devices to try to prevent police detection and prevent fines. Criminals use GPS jammers as a cover for vehicle theft or to avoid tolls or mileage charges. In the fleet world, drivers can use GPS scrambling to avoid employers knowing where they are going in a company vehicle.
