The Skywiper EDM4S C-UAS handheld jammer, displayed at DSEI 2023 in London, is widely used by the Ukrainian army. Its dimensions are 1,045 (L) × 350 (H) × 250 (W) mm. (Janes/Olivia Savage)
“Thousands” of Lithuanian counter-unmanned aircraft systems (C-UASs) are operational with the Ukrainian army, Ivan Sybyriakov, manager of the unmanned systems centre at Ukrainian state-owned SpetsTechnoExport (STE), told Janes .
The C-UAS solutions in question are the Skywiper Electronic Drone Mitigation 4 - System (EDM4S) and the Skywiper Omni, developed by Lithuanian company NT Service.
The Skywiper EDM4S solution, which disrupts the UAS's control, video, and global navigation satellite services (GNSS) signals, is considered by the user to be the “best option for the regular soldier” because of its long-range (3–5 km line-of-sight) and relatively light weight (6.5 kg), he said.
He added that price was also an important consideration.
The system can operate for up to 1 hour and disrupts UASs operating on 900 MHz, 2.4 and 5.8 GHz, as well as GNSS L1 1.5 GHz frequency bands. Other custom frequencies can be added depending on the customer and local regulation rules, Sybyriakov said.
Along with the handheld jammer, the army deploys the Skywiper Omni – an omnidirectional jammer that weighs11.3 kg and has a 500 m domed range. The system operates on the same frequency bands as the handheld jammer.
According to Sybyriakov, it is easy to use and is suited for mobile groups or in medical evacuation situations where the majority of vehicles are not armoured.
