What are GPS jammers and how do you combat them?
- by Micky
GPS finds major use in most equipment and systems to provide location information instantly both in civilian and military applications. These devices use the signal received from a minimum three GPS navigational satellites or more to calculate the location information. The use of GPS Systems helps terrorists to navigate both on land in mountains, jungles or desert terrain thereby providing them with a high degree of mobility and action capability.
If it doesn’t jam GPS reception beyond the confines of the vehicle its being used in, I see no problem with it. Specifically what’s probably happening is that the active antennas have ceramic bandpass filters centered on the GPS band, often on both the input and output side of the low-noise amplifier. This makes it look like there’s a “bump” of signal at the GPS frequency of 1.575GHz – outside of that passband very little gets through the filter. They have simcards which use GPS to track and trace where the vehicles are located. It sends periodical messages to the criminal then stolen and chopped.
Range is important, and it would have been useful to know the range of this device for jamming a cheap GPS. How hard would it have been to do a few tests to figure out how far out the jam field is effective? If it’s only a few feet, it’s hard to get one’s panties in a wad over it even if it’s technically illegal. If it’s thirty feet then yeah, you could be seriously inconveniencing people around you, much less cool. Some drones refuse to fly in city areas for safety and legal reasons; and these drones use GPS location to determine If they are in a city area or not.
While brouilleurs d ondes can cause minor disturbances, such as signal loss, they can also pose a large risk to public safety. For instance, GPS jammers cannot distinguish between types of communications and may block ingoing or outgoing calls from emergency responders. Additionally, the devices could block more than calls and disrupt all communications within a broad frequency range. By using orbiting satellites and radio signals, a receiver can determine the precise location of any GPS-enabled device or vehicle. Jamming occurs when a device emits radio signals at the same frequency as the GPS-enabled device.
OEM telematics Unlock the potential of embedded telematics data from one unified platform. Whether through integrated OEMs or installed hardware, Geotab has a number of options to connect and manage your fleet and asset data in a single platform.
In addition to mobile phone signals, the device can also block GPS, WiFi and other signals. Some may see GPS jammers as a means for drivers to sidestep telematics mandates and measures in order to gain a competitive edge, or because of concerns over personal privacy. GPS jamming devices also pose a significant risk to public safety and security. try this out https://brouilleurdonde.com/
Though the use of GPS jammers is illegal, and not common in the United States, they can still cause issues and risks for those in the transportation industry.

This little thing is clearly made for one purpose only and that is to disable any type of geofencing and vehicle tracking while a car is being stolen. This jammer seems to have a predicable period, I wonder if it’s possible to process the signal and cancel out the predictable signal? I’m sure the military radio wanks are reading this article and snickering. A receiver from prox 1980 had very little computational power, and also limited number of channels, usually two that were multiplexed between tracking satellites, and to receive and decode the ephemeris.
