Rating of the best jammers for GPS and GLONASS signals for 2020

With the global coverage of cellular, satellite and Internet networks, it is difficult to remain unnoticed. But sometimes it is vital to hide from observers. Progress does not stand still. The more satellites in orbit and cell towers on the surface, the more effectively any objects are tracked. But the more powerful and more perfect are the devices that oppose this. A huge number of modifications of various jammers have been created, which are successfully used to remove objects from observation.

Systems for determining the exact coordinates of an object were originally developed for military purposes, but with the development of technology, they became available, and most importantly, they are necessary in everyday life. A navigator is a useful and necessary thing for every driver. And for private carriers, the installation of trackers for monitoring is mandatory since 2013.

Two navigation systems

GLONASS - Russian and GPS - USA are used to track moving objects. They allow you to fix the coordinates, speed, direction of movement and fuel consumption.

The system is useful for the driver in that it will help to orientate in unfamiliar terrain, to plot a route. It gives logisticians control over the movement of cargo, deviations from the route, allows you to track the inappropriate use of the vehicle, fuel drain, etc.

Thanks to this system, there is an operational connection with the dispatcher, it is possible to wiretap the cabin. When a car is stolen, reliably hidden beacons allow you to quickly find the car, and in the event of an accident, the system independently sends a distress signal.

But sometimes situations arise when you need to hide your own location. To prevent the satellite from determining the coordinates of the object, radio signal suppressors or jammers are used.

What is GPS / GLONASS jammer for?

They are used when it is necessary to deviate from the route for hired road carriers, to conceal the fact of an unplanned parking, when avoiding pursuit or suspicion of wiretapping.

When installed in a car, a jammer blocks all radio signals within a radius of 5 to 15 meters. Therefore, you can be sure that the object will disappear from the field of view of observers.

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

How the satellite tracking system works

Both GPS and GLONASS have one principle of operation: tracking and analyzing the temporal and spatial coordinates of an object. The tracker or beacon installed in it receives a radio signal from the satellite. Using special modules, coordinates are automatically calculated, the calculations are based on data from nearby cell towers and nearby satellites. All movement data is accumulated in the tracker memory and then uploaded to the server.

Differences between GPS and GLONASS

The Russian GLONASS system has been in development since 1982, but development was stopped during perestroika and the collapse of the USSR. Work resumed only in the 2000s, and in 2015, the creation of the Global Navigation Satellite System was officially announced.

GPS (Global Positioning System), the global positioning system has developed more actively. The ban on limiting the accuracy of determination for civilian purposes was lifted much earlier, which significantly accelerated the development of the system.

The principle of building navigation systems is the same. There are satellites in low-earth orbit, they transmit a signal, and there are receivers on the ground. The coordinates of the radio signal receiver can be calculated from the 3 closest satellites, the location of which is always known exactly. With the help of the fourth satellite, you can determine the exact time, and for a moving object and speed. When receiving pulses from a larger number of satellites, the error of all indicators is reduced.

To implement monitoring at any arbitrary moment in time from any point on the earth's surface, from 5 to 12 satellites are available for radio communication.

GLONASS has launched 27 satellites into orbit, while 18 units are enough to fully cover the territory of the Russian Federation.

There are 32 satellites in service with GPS, and an additional 16 units are planned to be launched.

The difference is also observed in the location of the satellites and tracking stations themselves.

GLONASS and GPS operate on the transmission of conventional radio signals in very close ranges. But the frequency of the signals and the coding method for them are different.

The error in determining the location of the object is not more than a few meters.

GLONASS has a coverage of the territory of Russia - 100% and 70% of the surface of the globe. GPS works everywhere except for polar regions.

The systems complement each other, therefore GPS / GLONASS monitoring is increasingly used. With this approach, the error in determining all parameters is minimized. Therefore, most vehicles are equipped with integrated satellite tracking systems.

But, as already mentioned, the driver may have reasons why it is imperative to get out of surveillance. For this, jammers have been developed.

What are the signal suppressors?

For the purpose of exposure, mufflers are:

• satellite (navigation) blocking pulses from the satellite;
• cellular - block cellular communication:
• others - the radio broadcast, Wi-Fi channel, Bluetooth, etc .;
• universal.

By way of application:

• stationary (installed in the passenger compartment);
• portable or pocket (can be carried).

In appearance, navigation signal jammers are divided into three types:

• A conventional muffler that plugs into the car's cigarette lighter and has one antenna.

Devices of this type include the positions of our rating: GP-50, GP-55, Carcam signal jammer mini1, KT-GPS.

• A portable device with multiple antennas.

This is how Scorpio 120 G Pro, Carcam signal jammer PS-40, Owl GPS mini, Berkut 12, TX - N1 look like.

• Stationary device with a large number of antennas.

The photo shows Terminator 40.

The most popular car jammers of the GPS / GLONASS radio signal. But their installation is fraught with problems with finding a car in case of theft. After all, when this device is working, data on the location and direction of movement will not be available to anyone.

How does a car muffler work

The jammer clogs the airwaves with useless, empty signals, and in this noise it becomes impossible to distinguish real requests and responses between the satellite and the beacon.

A decisive role in assessing the quality of the device's operation is played by the power of the muffler, that is, the number of signals that it sends on the air, the range and frequency range.

GPS beacons use the 1575 MHz band, GLONASS - 1602 MHz.

Recently, however, experts say that the so-called jammer, that is, a primitive anti-tracker connected through a car cigarette lighter, is no longer so effective, since there are many cell towers in an urban environment. Object positioning is also possible by them, although its accuracy, of course, is not so high. In addition, the disappearance of the GPS signal from the tracker will automatically notify the tracking service of an attempt to hide the location of the object. Spoofers have appeared on the market to solve this problem. These devices do not jam, but rather generate additional false requests. The real signals are lost among the false ones, and positioning becomes impossible.

How to make an anti-tracker yourself

The simplest device that protects against wiretapping and tracking can be easily made by hand at home. The device consists of the main parts:

• generator;
• antennas;
• schemes;
• amplifier.

The generator creates oscillations, they go to the coil, the frequency spectrum depends on the number of turns of which.

For a person with basic skills in radio engineering, it is not difficult to understand how to make such a gadget, and there are many step-by-step instructions and tips on the Internet.

For those who still do not dare to test their abilities, select material for manufacturing and sit down at the soldering iron, there is always the opportunity to purchase the model you like in the online store.

And how much this or that device costs and which one is better to buy, the rating of the best jammers of GPS and GLONASS signals for 2020 will tell you.

How to choose a signal suppressor for a car

Before running to a store or ordering a product on AliExpress, you need to look at the quality rating, study recommendations, read reviews about popular models and new products. How to determine your own criteria for choosing a device can be prompted by detailed reviews and descriptions of goods on the Internet.

According to buyers, the best manufacturers of devices for vehicle protection can be identified. Among them there are both Chinese and Russian production:

• TX;
• KT GPS;
• Carcam;
• GP;
• Terminator;
• Scorpio;
• Veil;
• Golden eagle;
• Owl;
• Predator.

Which company is better and where to buy the device, customer reviews and product reviews will tell you.

But still, for yourself, you need to highlight some parameters that affect the popularity of models and by which the choice will be made.

frequency range

There are situations in which it is necessary to muffle all signals. And sometimes, just blocking navigation is enough, or vice versa, only mobile communication. A huge plus will be the ability to adjust the frequencies to be switched off.

Emitter power and range

These parameters are interrelated. The higher the power, the greater the radius of the device. The declared radius does not always coincide with the real one. This is due to the proximity to the object of cell towers. The closer they are, the more intensive the work on sending signals must go, the smaller the radius they cover. For many models, after listing the characteristics, a minimum radius of 1 meter is indicated, provided that they work in the immediate vicinity of the cell tower.

Autonomous operation and battery capacity

The amount of time a device can run on a single charge is often a deciding factor in a purchase.

Dimensions and weight

Large and heavy gadgets are not easy to hide in your car or carry in your pocket. The priority is light and compact devices. Often these types of devices are supplied from China, while domestic mufflers look more impressive.

Price

Many people make the mistake of choosing by price alone. But more expensive doesn't necessarily mean better. The cost depends on many parameters, including the spectrum of suppressed frequencies. But often, for use in everyday life, only a specific minimum is needed.Therefore, there is no point in overpaying tens of thousands for a universal "broadcast" device if you need an inexpensive, primitive jammer for a car interior. By the way, you can save a lot if you order the product you like online.

Equipment

All devices are shipped in packaging with:

• charger;
• adapter for car cigarette lighter;
• antennas (if available);
• instructions for use (can be downloaded online);
• Portable models come with a case.

Carefully studied characteristics and functionality of the selected models will help not to make mistakes when choosing.

There is often false information that jammers of satellite signals also act on traffic police cameras. But for this, the device must have a very large range and decent power. Suppressors of this type are quite expensive.
