UN raises alarm over increase in jamming and spoofing of satellite navigation systems

Increasing incidents of interference with aviation, maritime and other satellite telecommunications services mean states need to urgently enhance their protection of a critical radio-frequency band, the International Telecommunication Union (ITU), the International Civil Aviation Organization (ICAO), and International Maritime Organization (IMO) have said with “grave concern” in a joint statement.

These cases of harmful interference are in the form of jamming and spoofing that disrupt Global Navigation Satellite Systems (GNSS) operating in the frequency bands allocated to the Radio Navigation Satellite Service (RNSS).

The joint statement has been signed by the secretaries-general of the three UN specialised agencies.

IMO secretary-general Arsenio Dominguez said: “The safety of seafarers and shipping relies on the resilience of systems to support safe navigation and communication. Interference with Global Navigation Satellite Systems poses a serious risk to shipping activities, which could cause collisions and grounding. I urge all member states to act to protect these critical systems.”

ICAO secretary-general Juan Carlos Salazar said: “Radio Navigation Satellite Service interference can impact aircraft operations far beyond the immediate affected area, creating potential safety risks across multiple flight regions.”
