Electronic support
Search the spectrum, detect every emitter, recognise what it is and find where it is. Most of electronic warfare is listening.
About electronic warfare
The invisible
battlefield.
Everything we depend on now talks through the air. Jets, phones, ambulances, soldiers, drones. The radio spectrum is a front line you cannot see, and electronic warfare is the fight for it.

Who lives where
Hover or tap the spectrum. Mint bands keep society running; red bands are where hostile drones talk.
- Navigation
- Mobile phones
- Emergency radio
- Air traffic
- Power-grid timing

…and it all goes quiet.
The three disciplines
Listen. Deny.
Resist.
02 · Deny
Electronic attack
Use energy to deny, degrade or deceive an adversary's use of the spectrum: jamming a link, or feeding it false information.
03 · Resist
Electronic protection
Keep your own radios, radars and navigation working when someone tries to jam or deceive them.
Anatomy of a threat
How a drone
talks.
A small drone is a flying radio. Every link it uses is a clue, and a vulnerability. No single sensor sees all of it.
-
Control link
Radio · typically sub-GHz or 2.4 GHz
The pilot's commands. If it can be heard, the pilot can be located.
-
Video link
Radio · typically 5.8 GHz
What the drone sees, sent live to the pilot. The link that films the strike.
-
Satellite navigation
Radio · around 1.2–1.6 GHz
Position and time. Weak by nature, so it can be jammed or spoofed.
-
Mobile network
Radio · cellular bands
Some drones carry SIM cards to fly beyond the horizon.
No single sensor sees everything. That is why fusion matters.
Why now

already contested.

Try it
Jam it.
Or fool it.
A drone knows where it is because it hears satellites. Those signals arrive weaker than a phone a thousand kilometres away, so they are easy to drown out, and easy to imitate.
- Normal
- The drone hears the satellites, knows its position to a few metres and flies its planned route.
