Today, many trucking companies try to control their drivers by installing GPS/GLONASS systems, which enable them to determine the driver's location in real time. In any case, this situation is not pleasant for the driver, as all his actions and movements (“left trips”) are under the control of the employer. Naturally, any Russian person will try to find a loophole and cheat.
The first thing he will start typing in a search engine “how to cheat GLONASS?”. The very first lines of the search will give him the following results: “Buy GLONASS jammer”, ‘GPS signal suppressor’ and ‘GPS/GLONASS jammer for car to buy’. Accordingly, he will read the instructions, buy the jammer and start (try) to use it.

A GLONASS jammer, also known as a GPS jammer or GLONASS jammer, is a device designed to block or distort the signals of the GLONASS navigation system
GLONASS jammer is a device designed to block or jam the signal of the GLONASS GPS system. It can be used for various purposes, including banning the use of navigation receivers, transportation monitoring or limiting data transmission.
So, let's make it clear at once that the use of jammer does not give an opportunity to deceive the systems of transport monitoring and fuel consumption control. The jammer is designed to deceive the specialist who analyzes the data received from these systems.
When trying to fool the tracking systems, drivers usually have three key objectives:
- To make their presence invisible while they are making “left-handed” trips or violating route schedules;
- to hide the fact that fuel has been drained from their supervisor;
- to present their superiors with a fictitious appearance of work (as a variant, clearing snow from the territory while standing in one place).

Based on the step-by-step instructions of the Internet, the best option to fulfill these three purposes will be the purchase of a GPS / GLONASS jammer, through the use of which the car will allegedly disappear from the radar. Let's try to understand how effective jammers are, or all the secret sooner or later will be revealed.
Working principle of GLONASS jammers
Portable jammer GPS / GLONASS on any vehicle is a device (suppressor, “cigarette lighter”, USB-flash) used to suppress frequencies from satellite systems. According to numerous experts, the use of a GLONASS suppressor makes it impossible to track the location of the vehicle using satellite systems. It is not only about navigators, but also about trackers and bugs. The principle of operation of devices to suppress signals on the vehicle is to generate interference at the frequency at which they are transmitted. The higher the amplitude of the noise, the less likely the communication will be realized. The radius of influence of the interference will be higher. After connecting the device to the on-board network, the device begins to carry out the work of generating interference within a radius of up to fifteen meters. All jammers function in the L1 and L2 bands. When the device is activated, all gadgets that are used to determine the location of the position through the GPS channel are unable to receive a signal from the satellites. It is especially worth noting that even if the vehicle disappears from visibility, it has absolutely no effect on the other indicators of monitoring systems. The system continues to clearly display kilometers, drains and fueling, driver's condition assessment and many other parameters.
Avoid being cheated by a GLONASS jammer
As it was said above, when using GLONASS jammers, drivers try to deceive the person responsible for the operation of transportation monitoring systems, but NOT the system itself (it is impossible to deceive!). Responsible approach to their job duties of the operating personnel controlling the equipment operation 100% guarantees instant detection and prevention of interference in the monitoring program operation. Modern navigation satellite systems and control and measuring devices have been significantly improved. Our company offers to install the program “Montrans Online”, reducing to zero the impact of “jammers” and artisanal “screens”.⠀
Satellite trackers are equipped with built-in internal memory, the information is saved in case of impossibility to send it to the server of collection and monitoring. That is why data on fuel drainage or route evasion will not go unnoticed, even if the receiving terminal was disconnected from power supply or did not work due to signal suppression with the help of interference. ALL today's products of the company “Montrans” allow you to see on the graphs of the temporary “disappearance” of transport, so you can not cheat GLONASS. All actions are noted in the dispatching software. In particular, when using jammer, the signal disappearance usually occurred when the vehicle was used by a specific and certain driver. In this case, the signal disappears not immediately at the point of departure, but after some time after the start of the movement, can also suddenly appear and disappear. It is not very difficult to find out the driver: it is only necessary to send a checking person with him on a trip. In 99% of such cases, all the equipment starts to work as usual and the failures stop.
