Tracking interception mainly targeted by GPS jammers

This is a hand-held GPS satellite signal jammer designed with 2 antennas. It can block GPS L1 L2 signals. These two signals are commonly used signals. Most GPS positioning and navigation devices use this signal. Therefore, this device can stop the signal from the tracking device and ensure track safety. Because it adopts a small portable design, it is favored by the majority of drivers. It is very important to protect their whereabouts. Its effective interference radius is up to 15 meters, which is enough to protect your effective area and safe location. Provide car charger to make the car use more convenient.

GPS technology involves the main positioning and tracking technologies that are widely used today. We are no strangers to GPS. Our mobile phones and smart watches are all used for GPS technology. GPS is used for our daily positioning and navigation. Our cars also use GPS. Car GPS plays an important role in traffic management and car navigation. GPS is very good for our travels, but it can also be used to track and monitor. For us, gps jammer can reflect its importance to protect our privacy and security. For example, tracking is important to us. Protective equipment.

There are three types of GPS encryptors:

1. A GPS jammer that can block satellite signals (on the contrary, it will generate noise in the satellite frequency). The signal is always transmitted to the ground (or in the air) equipment at two main frequencies: the GPS frequency (for the civilian L1 band of the tracker) 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, it will cause interference on the frequency of the mobile operator. Operators operate at different frequencies according to modes (3G, 4G) and standards (GSM, DAMPS, CDMA). Therefore, several antennas are installed on the blocking device to close all ranges, and these antennas can work individually.

3) Universal jammer. It applies to all frequency bands, such as mobile operators and satellite signals. It has multiple antennas and can interfere in a selected range. It also often provides the possibility of selective operation, that is, the ability to generate noise only at selected frequencies (for example, only within the range of the cellular communication standard GSM 1800).
