GPS signal jamming and anti-drone

Permanent Linkby alexytony on Tue Oct 09, 2018 11:55 am

New approaches to fighting drones
As the drone threat has continued to evolve, the technology used to counter them has also matured. Early solutions which may seemed janky and offbeat (such as using birds) have given way to those rooted in existing military technology. One common setup appears to have evolved: which integrates modern radar, electro-optical sensing, and jamming technology in a complete anti-drone system.

What exactly do they intend to do with the drone cell phone signal jammer? Unless it's a really shitty drone it'll have rth on loss of discernable signal so unless that thing is relatively high power microwave (enough to overheat and destroy the internal electronics) then it's not going to do all too much aside from maybe forcing soft land if they don't have rth set correctly.
When does need drone GPS signal jammer?
If a drone is determined to be hostile and needs to be neutralized, the next phase is activated. Coaxial to the electro-optical sensors, powerful jammers are mounted that can jam the radio signals headed to the drone. Depending on the software, the drone might attempt to return to the operator (the path of which can be tracked on radar), land, or simply fly out of control. The ability for the drone’s operator to control it is expected to be completely degraded by most jammer systems if they are used within effective range.

The EWTV uses a 4x4 M1235 Mine-Resistant Ambush Protected (MRAP) armored truck to carry the complete electronic warfare package. We don’t know the exact specifications of the system, but SRC, Inc. is the supplier and has based it around a modified version of their AN/VLQ-12 Duke drone jammer, according to Breaking Defense.
Duke is an outgrowth of a U.S. Army development effort to defeat remote-controlled improvised explosive devices that began in 2005, known as Counter Radio Controlled Improvised Explosive Device Electronic Warfare, or CREW. The initial versions of the AN/VLQ-12 went into Humvees, MRAPs, and other Army armored and unarmored vehicles, to provide short-range jamming to prevent terrorists and insurgents from setting off those bombs with cell phones and other remote triggers.

The system with its narrow jamming cones has some capability to handle swarms by moving the jammer in a circular pattern, but this is not a robust capability. Using advanced radio transmitters such as those found in AESAs, which can shape the beam into distinct shapes, could aid with this.

Unfortunately, GPS has been mostly abandoned for guided weapons and fighter-jets for a while : advanced inertial navigation correlated with terrain recognition and stars mapping, visual acquisition of targets coupled with AI etc etc have became the trend for a while since such systems have simply no effect against it…

Note that there is another trend : having upgraded old remaining GPS weapons software. As soon as a GPS jammer is put on, the weapon guides itself on the source of jamming.
