A single day of GNSS outage is estimated to cost 1 billion dollars in US alone (1). GNSS is a reliable system, and to keep it as such professional GNSS receivers need to be wary of all possible vulnerabilities which could be exploited. Using GNSS receivers which are robust against jamming and spoofing is key for secure PNT (Positioning, Navigation and Time).
These cellular portable jammer are permanently controlled by a central administrator who can authorize or prohibit cellular communications. These cellular jammers are connected via a CAN (Controller Area Network) network in a local area network and managed by a central base station (CBS). The intelligent scrambling system controls everything from detection to alert when and where an individual cell phone tries to establish a call, to block calls.
More than a prison Jammer is a clever scrambling system. It can detect and block manually or automatically the unauthorized use of cell phones and / or the activity of mobile phones in designated areas. The cellular detector composition functions as a cellular detection center and can function as a managed access system or in conjunction with a series of cellular scrambling components.
It can also prevent GPS GPS location. If the GPS tracker hidden by thieves in our car, which is stupid and dangerous, we will oppose, otherwise we can not guarantee our safety. The scrambler signal / blocker signal in your car and make it work, it displays a false appearance of geolocation scrambler tracker. For example, you drove out of the garage, but the GPS tracker can not receive signals from the satellite, and therefore compatible with the credit history. 12 antennas cross work in all areas of work to make up the shortfall between them
After having activated the central locking of your car, do you check that the doors are closed? Indeed, the signal emitted by your remote key or your free-hand card can be scrambled remotely using electronic boxes that are easy to get. As a result, without knowing it, your car remains open and you can be the victim of a burglary-free flight. Here are our tips to avoid this attack.
