This is the electronic warfare that is helping Ukraine to stand up to Russia

The wars of this century are no longer won by whoever has the most cannons, but by whoever has the best technology. A clear example of this is what is happening in Ukraine, where electronic warfare, also called electromagnetic, is helping that country to stand up to Russia, an enemy that has an army five times the size.

It is an invisible and complex battle, on the airwaves, which allows fighting in a way that is very different from the conventional one, knowing the position of the enemy or leaving him incommunicado. Basically, electromagnetic warfare deals with everything that emits a signal: radios, radars, phones, GPS, or drones. For example, it has allowed the trajectory of the missile that fell this week in Poland to the location of enemy positions on the ground.

This is achieved thanks to the electromagnetic waves emitted by the radios, which the enemy soldiers use to communicate, but which give away their position.

Lieutenant Colonel Óscar Javier Gajete, head of a battalion in the Army's Electronic Warfare Regiment, REW 31, explains in statements to the Atlas agency the complexity of electromagnetic warfare. In what at first glance may seem like "a secarral", he indicates, "we with our equipment can simulate that there is the activity or that there is not." To do this, sensors are distributed that generate false communications, as if there were a camp.

The possibilities of electronic or electromagnetic warfare are vast: they can interfere with satellite signals, launch high-frequency waves that literally "fry" electronic circuits, even divert missiles, as has happened in Ukraine, or knock down remote-controlled drones at block the signal that directs it.

In this sense, there are cases that are astonishing, such as when Russia managed to locate a Ukrainian general by answering a mobile call, believing it was his mother. Seconds later, the Russians launched a guided missile at their position.

Another variant is also the so-called "navigation war", which disturbs the GPS signal. "It consists of acting on the positioning system, on the GPS of a ship or an airplane, and confusing it in its position, so that it does not know where it is", describes Gajete.

This type of warfare is being practiced in Ukraine and is the reason why some Russian planes carry two GPS systems to avoid getting lost.

Thanks in large part to NATO's electronic warfare measures, Ukraine has the initiative against a Russian army that outnumbers it but not technology.
