Jammers disturb GPS positioning: How to interrupt GPS positioning

GPS technology in the vehicle can be disturbed or completely blocked by so-called jammers. Electromagnetic waves superimpose the signals from the transmitter for a short or long term, making them unusable. To do this, the jammer simply has to be near the GPS device. The use of whining is generally prohibited in Germany.
However, such a disruption must be distinguished from the much more complex GPS spoofing, which not only disrupts the transmission, but also transmits completely manipulated data.

Employees feel they are being monitored

For a long time now, more and more vehicle fleets have increasingly used telematics systems, with the help of which daily work processes are increasingly digitized. This primarily includes GPS positioning. Their use can bring numerous advantages, both for the company and for the employees. However, it also happens here that employees feel permanently monitored with a telematics system in their vehicle: With the built-in technology, their locations can be viewed at any time and all routes driven are precisely recorded. In particular, those who were previously allowed to use a company vehicle freely feel that they are being monitored around the clock, their personal freedom is restricted and they are often treated unfairly.

At this point, however, they don't have a lot of options. Although they need to be informed about the use, they usually cannot refuse the technology. First and foremost, it serves the common good and has added value for the entire company. GPS may not be used for the pure monitoring of employees - especially not after work or on the weekend.

Interference with GPS not advisable

For some employees, with or without a reason, the following option seems attractive: With the help of jammers, vehicle tracking can be interrupted or even prevented entirely. However, this approach is by no means recommended. First, you will sooner or later notice that something is wrong with the GPS device. And secondly there is the fact that should not be ignored that jamming is prohibited in Germany. An employee who wants to prevent being located with a jammer is acting improperly when buying or using it. In particular, because the radiation can also interfere where it becomes dangerous, for example in ambulances or traffic control systems. The use of jammers can result in severe penalties. For some years now, the Federal Network Agency has even been taking action against illegal jamming. Administrative offenses can be punished with fines of up to 50,000 euros.

Attention: Use of disruptors in companies

As already said, the use of whining is punishable and not recommended. Sooner or later it becomes apparent that the technology is not working properly. This can possibly even lead to major problems in the vehicle fleet or in the company. In their own interest, employees and fleet managers should therefore observe the following points:

  • Avoid interference as far as possible
  • Check the location / status of the hardware regularly
  • Take a look at the online portal
  • Compare data such as mileage and time
  • Report any deviations if necessary

Protection against GPS jammers

There is almost no complete protection against GPS jammers. There is technology that can reduce the effect. However, this is cost-intensive and complex and is therefore used at most in areas such as the military or aviation. For medium-sized companies, however, they are rather impractical and not recommended. If, as the person responsible for the fleet, you notice inconsistencies or malfunctions in the GPS technology, you should definitely investigate and, last but not least, look for jammers. However, malfunctions caused by criminal energy cannot be prevented, for example in the event of theft or misuse of a vehicle. Regular checks of the hardware and software as well as quick action in the event of problems can usually prevent malfunctions. An open approach to technology also leaves employees feeling better.
