Signal Jammer Tech

According to Andrew Perpetua, an OSINT (open source intelligence) analyst who is independently sorting out equipment losses caused by the escalation of the Russian-Ukrainian war, data confirmed on the 18th showed that about 110 pieces

of Russian military equipment losses (destroyed, damaged, etc. abandoned, captured) were found. The number of casualties of the Ukrainian army was limited to about 25.

Perpetua commented that whether this was the highest number of Russian military equipment losses recorded in a single day, "I don't quite remember, but it's close." This is probably close to the largest gap in the number of losses

between the two sides in history. For each damage, Perpetua also lists the weapon that caused the damage (if known).

It is reported that the self-destructive FPV (first-person view) drone destroyed the most Russian military equipment so far that day. The Ukrainian military's FPV drones, which cost about $500 and are deployed about 100,000 per month,

damaged about 80 pieces of Russian military equipment. The Russian military seems unable to stop the attacks of Ukrainian military drones.

A recent exposé by a Russian military blogger shows why. Russian industry has produced a variety of signal jammer that can block communications between drones and their

pilots, but many of them don’t seem to work. The blogger angrily charged that $2,400 jammers being marketed on popular Telegram channels were not only useless, but harmful.

The jammers gave frontline troops a false sense of credibility, leading to their deaths. “It’s shocking to imagine how many soldiers have died because of false hope,” the blogger wrote. The multi-frequency jammer the blogger

dissected is not the first anti-drone jammer used by the Russian military on the front lines of the current two-and-a-half-year war, but it has proven

ineffective. In early April, a Ukrainian brigade conducted a daring three-night operation to capture an abandoned Russian tank equipped with a new type of jammer. It seems that this jammer didn’t do much either.

Using radio jamming devices to repel drones attacking critical infrastructure

A drone crashed near a Pennsylvania substation in July 2020, most likely with the goal of destroying the substation’s electronics. The drone was a modified multi-rotor aircraft manufactured by China's DJI Innovations.

Fortunately, the attack did not disrupt power supply or damage substation equipment, but it was the FBI and the Department of Homeland Security (DHS) that investigated the incident. The National Counterterrorism Center (NCTC)

concluded that this was "the first case of a modified drone attack on energy infrastructure in the United States."

Such attacks will continue to occur somewhere in the world. This is because relatively cheap commercial drones can be used to attack critical infrastructure.
