Satellite navigation systems are now part of daily life. Mobile phones are equipped with GPS chips, which are used by parking lot operators to locate luxury cars or luxury trucks that drivers and sailors rely on. But experts warned of the dangers faced by GPS and similar systems. Experts warned of the vulnerability of satellite navigation systems at a British conference hosted by the Digital Systems Knowledge Transfer Network and the Royal Navigation Institute. Cheap jammers can easily deceive recipients.
The Achilles heel of the Global Positioning System (GPS) is the weak signal from the satellite. David Last, the former dean of the Royal Navigation Institute, said in his speech that they orbit about 20,000 kilometers, but can only emit 100 watts, and the signal must reach 38% of the earth’s surface.
The low signal strength makes GPS sensitive to accidental gps blocker from solar wind or pirate transmitters. However, the system may also be deliberately destroyed by special transmitters. For example, 2 watts of transmit power is enough to confuse receivers a few meters away. This also applies to the Russian Glonass or the future European system Galileo.
The GPS jammer is already available online for about 30 euros. You are not allowed in this country/region. For example, they are used by car thieves: if they use this kind of jammer, even with GPS tracking equipment, they will never find the vehicle they stolen. According to reports, truck drivers on German roads tried to use this device to bypass the toll system. Terrorists can cause huge damage to this-according to Luster, devices have been found among terrorists.
The second threat is deception. It is claimed here that the GPS receiver is in the wrong position. The equipment required for this is still quite expensive. Several thousand euros must be spent for this. But Luster is worried that this situation will change, and criminals will have this device sooner or later.
An experiment conducted by the British Lighthouse Authority, the General Lighthouse Authority (GLA) in 2008 showed that jammers posed a danger: relatively weak jamming signals, GLA sent off the east coast of England, caused the ship’s location system to fall into Dilemma. Some suddenly found the ship near Ireland, others near Scandinavia. Others claimed that the ship sailed on land at an alarming speed.
GLA employee Alan Grant explained that the biggest danger here is not from absurd loopholes, but from small deviations that the sailors barely notice. To make matters worse, many people now rely on navigation systems to the point that they forget how to use charts, asterisks or paddock navigation to determine traditional locations. Satellite navigation is like the first computer before it was infected by a virus, adding to the burden. Unlike computers, no company in this field is responsible for security, which brings new problems to users. Navigation is no longer just to determine your own location, it’s easy. “Now it is reliable, safe and stable to operate.”
