They can be used when one needs to deviate from the route of a leased road carrier, hide the fact of unplanned parking, evade pursuit or suspect wiretapping.

　　When installed in a car, the anti tracker gps blocker all radio signals within a 5 to 15 meter radius. So you can be sure that the object will disappear from the viewer's field of view.

　　In order to understand how to choose the right jammer and what to look for when buying, you need to understand the equipment of your navigation system.

　　How satellite tracking systems work

　　GPS and GLONASS work on the same principle: tracking and analyzing the time and space coordinates of objects. Trackers or beacons installed in it receive radio signals from satellites. With the help of special modules, coordinates are automatically calculated based on data from nearby base stations and nearby satellites. All exercise data is stored in the tracker's memory and then uploaded to the server.

　　Difference Between GPS and GLONASS

　　The Russian GLONASS system has been in development since 1982, but stopped during the reforms and the collapse of the Soviet Union. Work did not resume until the 2000s, when the establishment of a global navigation satellite system was officially announced in 2015.

　　The development of GPS (Global Positioning System) is relatively active. The earlier lifting of the ban on civilian measurement accuracy greatly accelerated the development of the system.

　　The navigation system is built on the same principle. There are satellites in low-Earth orbit, they transmit signals, and there are receiving equipment on the ground. The coordinates of the radio signal receiver can be calculated from the nearest 3 satellites and their positions are always accurate. With the fourth satellite, you can determine the exact time, as well as the speed and velocity of moving objects. Errors in all metrics are reduced when pulses from a large number of satellites are received.

　　For monitoring from any point on the Earth's surface at any point in time, 5 to 12 satellites can be used for radio communication.

　　GLONASS has 27 satellites in orbit, and 18 satellites are sufficient to cover the entire territory of the Russian Federation.

　　GPS has 32 satellites in operation and plans to launch 16 more.

　　Differences can also be observed in the location of the satellites themselves and the tracking stations.

　　GLONASS and GPS transmit regular radio signals at very close range. But the frequencies of the signals and how they are encoded are different.

　　The error in determining the position of an object is no more than a few meters.

　　GLONASS has a certain degree of coverage of Russian territory - 100% and 70% of the Earth's surface. GPS can be used anywhere but the polar regions.

　　These systems complement each other and are therefore increasingly monitored using GPS/GLONASS. Errors in determining all parameters in this way are minimized. Therefore, most vehicles are equipped with sophisticated satellite tracking systems.

　　However, as already mentioned, drivers may have reasons why it is very necessary to get out of surveillance. That's what the jammers gps is designed for.
