FPV drones have risen from an obscure hobby of racing drones to the mass production of millions and dominance of the Ukrainian battlefield.
However, cheap but lethal FPVs are rapidly being assimilated by terrorist and separatist organizations, cartels, and criminal gangs.
1/ Image In the Sahel, al-Qaeda-linked Jama’at Nusrat al-Islam wal-Muslimin (JNIM) has used FPV drones armed with explosive warheads against fortified positions.
This marks a significant shift from indirect IED warfare to long-range precision-guided strikes.

Fresnel zones significantly affect control and video communications with FPV drones.
Fresnel zones are volumes of space between a transmitter and receiver in which any obstacles interfere with a signal even if radio line-of-sight (LOS) is clear.
1/ Image Trees, buildings, terrain, and even vehicles within this zone can interfere because radio waves propagate as expanding wavefronts.
Waves therefore arrive at the receiver via slightly different paths, but they interfere constructively if the zone is clear.

Russian blogger Ilya Mersh (“Older than the Edda”) focuses on a dilemma for the West—that its potential adversary produces the best components that are required to keep pace with the drone revolution.

“The current drone revolution is interesting for one important reason.

Canada has donated 89 new “ASCV” (Armored Combat Support Vehicles) with really modern technology and protection to Ukraine, but apparently they haven’t fared well.
Problems include excessive weight (29.5 tons), leading to increased tire wear and ruptures in intense conditions.
1/ Image Critically, its electronic visibility due to the abundance of emitting equipment increases the EM signature, making it easier to detect with radio reconnaissance.
The high electrical consumption of the electronics creates a huge load on the batteries.

The RAND corporation has published a study of whether directed energy weapons (DEW) can be useful in Ukraine.
The study concluded that neither high-energy lasers (HEL) nor high-powered microwave systems (HPM) in their current state of development are suitable for Ukraine.
1/ Image The technological readiness level (TRL) for HEL or HPM systems varies, but none are ready for mass production.
DEW weapons require enormous amounts of power, and lasers generate huge amounts of heat.
Atmospheric conditions can also significantly limit HEL effectiveness.

This Russian “Geran-2” (Shahed) has a new antenna, apparently for navigation using radio beacons.
Ground-based VHF omnidirectional azimuth radio beacons (VOF) broadcast a reference signal in the 108–118 MHz range, while encoding azimuth bearing in a rotating variable signal.
1/ Image The azimuth (radial angle) from the UAV to the station is determined by the phase difference between the reference signal and the narrowly directed variable signal.
This may be paired with DME (Distance Measuring Equipment) for a full position fix, independent of GPS.

Logistics to the Ukrainian frontlines is increasingly being supplied by UGVs and heavy multirotor drones.
In one assault brigade, up to 40 tons per week are sent this way, representing 80% of total logistics delivered.
1/ UGVs in particular are replacing traditional logistics involving infantry and vehicular transport, which can no longer survive in the 20 km grey zone of constant aerial surveillance and FPV strikes.
Drones are attritable and save Ukrainian lives by replacing men with machines.

More Russian “Gerbera” reconnaissance UAVs are armed with OFBCh-2 fragmentation warheads.
The inertial impact UZ-2 fuze is also used on OFZBCh-50 “Geran-2” warheads.
The fuze is armed by the UAV's flight controller (FC) shortly before impact, likely prompted by altitude.
