Perhaps many people know that GPS signal jammers were originally developed by the military to mislead the enemy's information about geographic locations and targets. The device is then tailored for consumers who want to protect their privacy or prevent tracking. Without proper technical knowledge, or improper operation, GPS jammers may cause harmful communication interruptions.
LMADIS seemed to blow up the circuit of an Iranian drone last week. This is the first "lethality" of the US directed energy weapon, but this is not always the expected result. Clark said: “UAVs usually return to base or land somewhere in a standard pattern.” The system is powerful enough that in smaller drones, the jammer’s electronics can interfere with the drone’s operation. Electronic devices, if they are close enough, can cause malfunctions. But usually jammers are only used to disrupt communications. "
US military officials said that the Marine Corps dune buggy jammer may have shot down two Iranian drones in the Strait of Hormuz.
Although LADIIS has all the advantages, they still have some blind spots. For example, it is relatively ineffective against fully autonomous drones. When there is no communication at all, interference is not very useful. It will destroy large drones instead of destroying them. And there may be friendly fires. For example, nearby American helicopters may find that their communications are interrupted by RF explosions. Therefore, despite the recent success of the LADIS system, it should still be regarded as the first phase of an ambitious project.
The GPS jammer itself is usually a small independent frequency transmitter that can send interference signals within a range of 5 to 10 meters. These devices are usually plugged into a cigarette lighter or USB/charging port and require almost no power supply. Although GPS jammers are illegal in most places, they can be purchased online and appear in many forms, such as: B. Wi-Fi jammers, Bluetooth jammers, remote control jammers or drone jammers.
GPS jammers may cause minor interference, such as signal loss, but they may also pose a major risk to public safety. For example, GPS jammers cannot distinguish communication types, nor can they prevent incoming or outgoing calls from emergency responders. In addition, these devices can do a lot more than just block calls and interrupt all communications over a wide frequency range.
