Aviation Tech Backup Urgently Needed as Satellite Interference Escalates, IATA Warns

The International Air Transport Association (IATA) has issued an urgent call for aviation authorities and operators to deploy resilient technological backups, warning that escalating interference with satellite navigation systems threatens the baseline reliability of modern flight operations. Speaking at the opening of the IATA World Safety and Operations Conference, IATA Director of Safety Mark Searle underscored that protecting global air transport requires deeper integration of people, advanced technology, and harmonised operational standards.

A primary driver of concern is the sharp spike in disruption to Global Navigation Satellite Systems (GNSS), which encompass widely relied-upon constellations such as GPS. The scale of the challenge has grown markedly in recent years. Reported GNSS jamming incidents increased by 67 per cent in 2025 compared to 2023 levels, while reports of GPS spoofing rose by a staggering 193 per cent over the same period.

While jamming blocks satellite signals entirely, forcing flight decks to recognise the loss of navigation inputs, spoofing poses a more complex operational hazard. Spoofing transmits false positioning coordinates that can masquerade as legitimate data, misleading onboard instruments without immediately alerting flight crews to the deception. In response, international safety leaders are stressing the critical necessity of secondary navigation systems and clear operating protocols when primary satellite links become degraded or compromised.

“The rise in Global Navigation Satellite System interference is a reminder that technology must always be supported by redundancy, procedures, training, and human judgment,” Searle noted.

Aviation safety performance has seen substantial long-term gains, with fatal accident rates continuing to show measurable improvement globally over past decades. However, maintaining that trajectory amid evolving electronic warfare, regional conflicts, and geopolitical tensions demands forward-looking safeguards. According to IATA, emerging digital tools can assist airlines in detecting risks earlier and triggering preventative action before an emerging threat turns into an accident. Nevertheless, industry leaders stress that automation cannot function in isolation.

To combat the growing disruption, IATA partnered with the European Union Aviation Safety Agency (EASA) to launch a dedicated GNSS Resilience Plan. The collaborative initiative is structured around four primary pillars:

• Monitoring and Reporting: Establishing standardised mechanisms to capture and share interference occurrences across carriers and airspace sectors in real time.
• Prevention Tools: Developing onboard algorithms and equipment safeguards to identify, isolate, and reject falsified satellite signals.
• Backup Infrastructure: Preserving and modernising conventional, ground-based navigation aids to guarantee uninterrupted aircraft guidance during satellite outages.
• Civil-Military Coordination: Enhancing direct communication between civil aviation regulators and military authorities to prevent test signals or defensive electronic warfare from spilling into commercial airspace corridors.

The campaign has gained momentum within the wider United Nations framework. The International Civil Aviation Organization (ICAO) has taken the resilience framework forward, explicitly condemning State-origin interference with civil aviation frequencies and establishing a global roadmap to preserve navigation integrity.

As commercial aviation integrates increasingly automated flight-management software and tighter airspace routing, the industry's exposure to electronic disruption grows. The clear consensus emerging from the World Safety and Operations Conference is that technology alone cannot resolve the vulnerability. Safeguarding modern airways requires a robust technological backstop, verified alternative navigation infrastructure, and continuous investment in the human expertise commanding the cockpit.
