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 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 under 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 is suitable for 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).
When the GPS device was created, it was very popular among militants and government agencies. However, the use of GPS in daily life is becoming common. In addition, GPS can protect your family and friends by tracking their real-time location and displaying it on a private map. Therefore, parents can find the location of their children at any time. The production process of some factories is carried out through GPS equipment. However, GPS use also has negative aspects. Thieves and other lawbreakers use GPS for illegal activities: tracking someone's location without their consent.
If you feel that someone is tracking your location, let us introduce you to tools such as GPS jammers. You can record every minute of a private conversation and show your location. Therefore, when you want to ensure that you and your privacy are protected, a GPS jammer is what you need. With this device, all "enemies" will not compromise your privacy.
GPS blocker is specifically used to disable GPS interception signals. The jammer can be used to block various GPS tracking devices and block satellite tracking communications. It should be noted that GPS jammers will not interfere with mobile phone signals. This kind of blocker is very convenient to carry because of its small size and light weight. In addition, you can use an external battery as a power source or car power source.
