“Pokrova” radio-electronic warfare system, This missile, used on Ukrainian territory, helps destroy Russian high-precision missiles and unmanned aerial vehicles, knocking them off course and making them visible to the air defense system.

Andriy Starikov, head of the electronic warfare department of the General Directorate of Electronics and Cyber ​​Defense of the General Staff of the Armed Forces of Ukraine, explained why it is so important to use EW systems in the current situation – ” Any device that uses the electromagnetic spectrum for its operation can be affected by electronic warfare. These are land vehicles, marine based drones and high-precision weapons such as cruise missiles or Shahed drones.”

The cruise missiles that Russia constantly bombs Ukraine with can be disabled thanks to such a mechanism. This is achieved by blocking onboard systems, in particular satellite navigation. Each cruise missile is equipped with a satellite navigation guidance system. However, there is also an inertial system that points to the target but has a large margin of error. The satellite navigation system works to reduce this error. Determines and sets the exact location.

If it is fraudulently intercepted or tricked, the positioning error will increase and the inertial system will accumulate false data while within range of this EW signal. Thus, the cruise missile becomes not a means of high-precision defeat, but ordinary ammunition. In addition, under the influence of the EH system signal, the cruise missile gains altitude and becomes visible to air defense systems.

It is also possible to fight against Iranian Shahid UAVs, which Russia uses to attack civilians and critical infrastructure facilities in Ukraine. In order for the inertial system to continuously accumulate error, the UAV must be affected from three sides along the entire flight path.

The system is capable of altering the satellite radio navigation area, interfering with satellite radio navigation along the entire battle line and most of Ukrainian territory. This means that not only in front-line regions, but in all regions of Ukraine, all systems using satellite navigation do not work at the time of activation. More precisely, these systems may not work if the Pokrova system is configured to suppress signals or display incorrect data when there is a change in coordinates.
