President's adviser explains how Russian Iskander missiles bypass GPS jamming

Mechanism of bypassing electronic warfare

Russian forces continue to attack infrastructure in Ukraine, including bridges, using Iskander ballistic missiles. Despite large-scale jamming of satellite navigation over the country's territory, the adversary manages to achieve high accuracy in its strikes. Serhiy Beskrestnov, the President of Ukraine's adviser on the development of defence technology sectors, known by the callsign "Flash", provided details on this process.

According to the expert, to increase accuracy, the Russians install special guidance heads on the missiles. These devices make it possible to correct the flight trajectory directly while approaching the target.

«На жаль, противник дуже влучно вражає мости. Як це йому вдається?» ("Unfortunately, the adversary is hitting bridges very accurately. How does he manage to do this?") — noted Beskrestnov.

Technical features of guidance

During air raid alerts over Ukraine, powerful jamming of navigation systems takes place. Under such conditions, the standard inertial guidance system of the Iskander missile cannot independently ensure a hit with metre-level accuracy. Therefore, Russian missiles are equipped with special guidance heads.

The following options are considered:

• 9E436 optical correlation guidance systems;
• 9B918 optical systems;
• heads with radar guidance.

As explained by "Flash", at the final stage of flight, when the warhead begins to move down towards the target, scanning of the terrain takes place over a few seconds. The data obtained allows the guidance system to make necessary corrections to the trajectory, ensuring a precise strike.

Consequences of the attack on Kyiv

It was previously reported that the Northern Bridge in Kyiv was damaged as a result of a Russian strike on the night of 7 November. Traffic on the overpass was completely blocked in both directions. According to the capital's mayor, Vitali Klitschko, specialists were working on site to assess the extent of the damage.

In addition to the bridge itself, the explosion damaged the road surface, the trolleybus contact line, and the power line. The shockwave affected five trucks parked nearby. Due to traffic restrictions, public transport temporarily changed its routes: buses and trolleybuses that previously operated across the Northern Bridge were diverted via the Podilskyi Bridge crossing.
