Unique devices commonly referred to as GPS jammer (suppressors or GPS blockers) that have recently appeared in the electronic navigation system industry. The task of these portable gps jammer devices is to prevent any attempts to identify the exact location by using GPS tracking. In this article, we will provide you with the opportunity to view the short gps jammer review. The GPS signal jamming system is designed to suppress the signals of the global satellite navigation GPS system in the range of 1500-1600MHz. The jammer makes it impossible for GPS satellites to monitor the location of cars and all vehicles through GPS, and the GPS jammer device will not interfere with mobile phones and other devices. Gps jammers can range from 5 to 15 meters, which is sufficient for cars and trucks and buses, because the tracker is usually installed in the cab inside the car. After starting the connection through the car cigarette lighter, the device immediately starts to work and generates radio noise (interference) in the range of 1500-1600 MHz (L1/L2) within a 15-meter radius. These are the basic frequency bands. They are all GPS-enabled devices, including trackers that can track all coordinates. After turning on the navigation blocker, all trackers that can use GPS to identify your location stop receiving signals and disappear from the monitor screen.
More and more people often face illegal GPS tracking, therefore, GPS signal suppressor (jammer) can be a practical help to prevent any spy tracking attempts of the GPS tracker signal installed in your car . The gps jammer can be powered by the cigarette lighter in the car. Very convenient and compact device that can suppress GPS signals. The working principle of the anti-gps system is to interfere with the transmission frequency of the useful signal. The greater the amplitude of the power noise generator, the less likely it is to realize the connection of the noise generating frequency, and the greater the influence radius of interference.
There are three types of GPS scramblers:
1. GPS jammer, which blocks satellite signals (on the contrary, it generates noise in the satellite frequency). The signal is always transmitted to devices located on the ground (or in the air) at two main frequencies: the frequency GPS (the civilian L1 frequency band used for trackers) is 1575.42 MHz. Frequency GLONASS (civilian L1 frequency band, used for trackers): 1602 MHz. Since the frequencies are very close, they are blocked by the broadband noise generator and only one antenna is required.
2) GSM jammer, which produces interference on the frequency of the mobile operator. Operators work on different frequencies, depending on the mode (3G, 4G) and standard (GSM, DAMPS, CDMA). Therefore, several antennas are installed on the blocking device to close all ranges, and these antennas work separately.
3) Universal jammer. It applies to all frequency bands, such as mobile operators and satellite signals. It has multiple antennas to generate interference in the selected range. It also often offers the possibility of selective operation, that is, the ability to generate noise only on selected frequencies (for example only within the range of the cellular communication standard GSM 1800).
Please note that if you use GPS jammers for personal safety and privacy, it is legal to use GPS jammers, but if you deprive a third party of the ability to use various GPS signals, you are breaking the law.
