RF Jamming vs. GNSS Spoofing: Choosing the Right Counter-UAS Layer

Counter-UAS programmes rarely fail because a technology is weak. They fail because teams stack layers without understanding what each one defeats. RF jamming denies the command link; GNSS spoofing feeds false position data. Used together they create pressure on both the operator and the autopilot.

Jamming is broad and immediate but can be detected through spectrum monitoring and may affect friendly links. Spoofing is quieter and preserves the ability to steer a target away from a protected area, yet it depends on the drone relying on satellite positioning.

A practical rule: use detection to classify the threat, jamming to break control when the link matters, and spoofing when you need a controlled outcome. Document the legal basis for each layer before deployment.
