Drone development and threats
With the rapid development of drone technology, drones are increasingly used in various fields. From agriculture to logistics, from film and television shooting to military reconnaissance, the existence of drones has greatly improved efficiency and convenience. However, it is precisely because of the widespread use of drones that some individuals and groups have begun to use drones for malicious activities. signal jammer These activities not only threaten public safety, but may also pose a serious threat to national security.
The rise of anti-drone technology
In response to the malicious use of drones, countries and companies have invested resources to develop anti-drone technology. cell phone jammer Anti-drone technology has also developed rapidly, mainly including drone guns, anti-drone shooting, attack birds, network artillery, lasers, missiles, GPS jammers, and radio transmitters. Among them, jamming technology is particularly important because it can effectively prevent drone actions without causing physical damage.
Classification and application of jamming technology
At present, jamming technology mainly includes three methods: radio frequency interference, global navigation satellite system (GNSS) interference, and spoofing.
RF interference: RF interference causes drones to lose control or return by destroying the communication link between drones and their operators. This method is widely used in the military and security fields and can effectively deal with various types of drone threats.
GNSS jamming: GNSS jamming blocks the communication between drones and satellites, making drones lose their navigation capabilities. Drones that lose navigation usually hover in place, land automatically, or try to return. This method is effective when dealing with remotely controlled drones。
