GPS signal jammers were originally developed by the military to mislead the enemy about geographic location and targets. Then these devices are tailored for consumers who want to protect their privacy or prevent persecution. Without proper technical knowledge, or if used improperly, GPS jammers can cause harmful communication problems.
This means that LMADIS apparently broke the circuit of Iranian drones last week. This is the first "kill" of weapons provided by the United States, but this is not always the expected result. Clark said: "Drones usually return to base or land somewhere in some standard mode." The system is Powerful enough that in smaller drones, the electronic equipment of the jammer will interfere with the drone's Electronic devices that are close enough will cause malfunctions. But usually jammers are only used to disrupt communication. "
The US military said that the Marine Corps dune buggy may have shot down two Iranian drones in the Strait of Hormuz. Although LMADIS has all the advantages, there are still some blind spots. For example, it is relatively ineffective against fully autonomous drones. If there is no communication at all, interference is not very useful. It will destroy large drones instead of destroying them. And there may be a friendly fire. For example, a nearby American helicopter may find its communication cut off by the RF explosive wing. Therefore, despite the recent success of the LMADIS system, it should be regarded as the first phase of an ambitious project.
The GPS Jammers itself is usually a small, independent frequency transmitter that can send out interference signals within ten meters of the top five within a certain range. These devices are usually connected to cigarette lighters or USB/charging ports, and require little Power . Although GPS jammers are illegal in most areas, they can be purchased online and in a variety of styles, such as B. Wi-Fi jammers, Bluetooth jammers, remote jammers, or drone jammers.
GPS jammers may cause minor interference, such as signal loss, but may also pose a significant public safety risk. For example, GPS jammers cannot distinguish communication types, nor can they stop calls from emergency personnel. In addition, these devices can not only block calls, but also interfere with all communications over a wide frequency range.
