GNSS Jamming

GNSS Jamming is the deliberate transmission of radio frequency signals designed to interfere with and disrupt the reception of Global Navigation Satellite Systems (GNSS) like GPS, GLONASS, and Galileo. Jammers broadcast noise on the same frequencies used by these satellites, overwhelming the much weaker legitimate signals. This prevents GNSS receivers in devices—from smartphones and vehicles to military drones and smart munitions—from calculating an accurate position, velocity, or time. While a significant threat to critical infrastructure and modern military operations, controlled jamming is also used by military and security forces for electronic warfare, to protect against GNSS-guided threats, and to test the resilience of friendly systems in training environments.

Key Features:

• Targeted interference on L1, L2, and L5 satellite navigation bands.

• Ranges from simple, low-power devices to sophisticated military-grade systems.

• Creates a localized “denial bubble” where GNSS services are unavailable.

• Disables navigation, tracking, and timing for all devices within its range.

• A primary tool for testing system resilience and conducting electronic attack (EA).

• Poses a significant risk to aviation, maritime, and ground transportation safety.
