LTV - protidronová puška ЕDМ4S Sky Wiper (přenosné zařízení REB)

Lithuanian anti-drone jammer EDM4S Sky Wiper (portable equipment REW)
Portable jammer Sky Wiper
In 2019, the Lithuanian company NT Service exhibited the electronic non-lethal weapon EDM4S, which is intended for the destruction of small and medium-sized UAVs.
The fully mobile device is designed to face remote controlled aircraft (RPAS) systems. The device is able to identify and actively disrupt UAV guidance, tracking and navigation systems. All elements of the EDM4S are fully integrated and ready for immediate use using a rifle trigger. A system adapted to work with other frequencies can be supplied on request.


The Lithuanian company TN Service demonstrated the EDM4S Sky Wiper at several exhibitions:
In March 2019 at the Security & Counter Terror Expo (SCTE) in London.
In September 2019 at the Defense and Security Equipment International (DSEI) exhibition in London.
In October 2021 at the Live Firing Show (LFS) in the Lithuanian city of Pabrade.


The EDM4S jammer is intended for use by security forces.
The EDM4S system is operationally safe and is listed in the NMCRL.
The Ukrainian Armed Forces have ordered an anti-aircraft jammer type EDM4S-UA.


Activity description
The operator points the EDM4S jammer at the selected target and presses the trigger. The transmitted electromagnetic pulse disrupts any communication with the UAV. The drone thus disturbed may interrupt the flight and land, or it may return to the place of take-off with the cargo. (1)

Notes of consultants:
(1)
This is a problem. Most drones have this function - ie. after losing the control signal, it "returns" home. Experience is such that an experienced operator can place the coordinates "home" on the target, if it is a static target. Another defense is the so-calledan inertial guidance system which, after losing the GPS signal, guides the drone along the programmed path. Both of these systems are less accurate than operator navigation, however, they can hit a surface target, such as a military base, even at the cost of a lower level of target damage.
(2)
GPS uses frequencies in the L1 band 1575.42 MHz and L2 1227.6 MHz. In addition, the newer generation also has the band 1176.45 MHz.
(3)
The 433 MHz band is mostly used for communication solutions at short and medium distances up to 300 m. It is used to connect eg a weather station with a wireless outdoor sensor, various wireless keys, gate controls, etc. Use in a drone jammer does not make sense.
GSM band for 2G networks. This makes sense for controlling and transmitting the image, but it won't do much


Short summary:
EDM4S Sky Wiper - It may work, but probably not miraculously, the drone could be "confused" after the disturbance, but it is a question of how much it would prevent him from completing the task.
