GPS jamming is a real issue for many motorists in South Africa. This FAQ will answer all your questions on GPS jamming, from how they work to how you can outsmart thieves who use them to keep your vehicle safe.
Wireless trackers, also known as portable GPS trackers, are small, battery-powered devices that show a vehicle's real-time location. They’re also wireless and don't need installation. They can fit into any vehicle and are often placed in strategic areas where vehicle thieves can’t locate them.
GPS jamming happens when someone uses a radio frequency (RF) transmitter to deliberately mess with GPS signals in a vehicle, which we need for navigation, timing, and positioning. We call these RF transmitters GPS jammers.
GPS jammers blast out stronger signals at the same frequency as GPS satellites. This noise messes with the GPS receiver, making it "blind" and unable to pick up accurate location data. It’s like someone yelling during a quiet chat—the device can't "hear" the satellites because the jammer is drowning them out.
A backup Cartrack tracker is a Cartrack Tag. It doesn't rely on cellular networks, making it perfect for preventing theft with signal-jamming tech. Plus, it's wireless, so installation is simple because there’s no complicated wiring needed.
Cartrack outsmarts GPS jamming through its Cartrack Tag. The Cartrack Tag operates on its own by tapping into Cartrack’s unique RF communication network for location updates. The Cartrack Tag adds an extra layer of protection. It works independently of cellular networks, making it perfect for situations where thieves use signal jamming to steal vehicles.
There are a few signs that your tracking device is being GPS jammed. Such as:
The range of a GPS jammer depends on its power output, which influences how far its signal interference travels. Compact portable jammers can disrupt signals within a few metres, while military and industrial jammers create interference that can reach up to several kilometres.
Yes, with Cartrack’s Tag you can! When paired up with a Cartrack tracking device, the Cartrack-Tag detects any signal interference during a vehicle theft and alerts our control room. This tech helps us locate your vehicle, even if criminals try to block our signals.
The three types of jamming are:
With jamming devices, yes, Cartrack’s tracking devices can be blocked. However, we have additional safety measures in place, like the Cartrack-Tag, to counter any signal jammers, making jamming much more unlikely. Less advanced tracking devices are much easier for criminals to block.
Cartrack starts at R99 a month for basic stolen vehicle recovery, with pricier plans offering more features.
Yes, you can have more than 2 tracking devices installed in your car to add an extra layer of protection. The Cartrack Tag is a solution that remains unaffected by any form of signal jamming, ensuring that your vehicle will be found, despite signal-blocking attempts.
