AIRTEL ATN LIMITED

Their core work

Airtel ATN is an Irish SME specializing in aeronautical communication, navigation, and surveillance (CNS) systems for air traffic management. They develop and integrate ATN (Aeronautical Telecommunication Network) solutions within Europe's SESAR programme, contributing to the modernization of airspace infrastructure across 31 H2020 projects. Their work spans datalink communications (CPDLC, ADS-C), surveillance technologies, and system-wide information management (SWIM), making them a consistent technical contributor to virtually every major SESAR work package. They bridge the gap between ATM architecture design and the communication infrastructure that makes it work.

What they specialise in

How they've shifted over time

In the early SESAR Wave 1 period (2014–2019), Airtel ATN focused on foundational ATM infrastructure: demand-capacity balancing, airport surface management, runway throughput, and essential CNS systems. Their work centred on making existing air traffic operations more efficient. From 2019 onward (Wave 2 and Wave 3), their focus shifted decisively toward next-generation ATM architecture — trajectory-based operations, LDACS digital communications, ADS-C surveillance, RPAS integration, and virtual centre concepts. This evolution mirrors the SESAR programme's own progression from optimizing today's ATM to building tomorrow's digital airspace.

Airtel ATN is moving toward next-generation digital communication (LDACS, ATN-IPS) and virtualised ATM, positioning them for SESAR 3 and the Digital European Sky.

How they like to work

Airtel ATN operates exclusively as a participant — across 31 projects they have never coordinated, which is typical for specialist SMEs in the large SESAR consortium structure where coordination is handled by major ANSPs or EUROCONTROL. With 194 unique consortium partners across 27 countries, they are deeply embedded in Europe's ATM research ecosystem. Their presence in nearly every major SESAR work package suggests they are a trusted, go-to partner for CNS/ATM integration, valued for specific technical contributions rather than project leadership.

Extensively networked across the European ATM community with 194 unique partners in 27 countries, spanning air navigation service providers, research centres, airports, and aviation technology companies involved in the SESAR programme.

What sets them apart

Airtel ATN occupies a distinctive niche as an Irish SME with deep, sustained involvement across the entire SESAR programme — very few small companies participate in 31 ATM research projects. Their specialization in aeronautical telecommunication networks (ATN/datalink) gives them technical depth that larger system integrators often lack at the protocol level. For consortium builders, they bring proven CNS integration expertise with the agility of a small company and an unmatched track record of reliable delivery across SESAR Wave 1, Wave 2, and Wave 3.

Highlights from their portfolio

• GAM-2020-SYS
  Largest single EC contribution (€875,000) — a Systems ITD grant indicating Airtel's role as a key systems integrator within the SESAR technology demonstrator framework.
• PJ14-W2 I-CNSS
  Second-largest funding (€475,377) focused on next-gen integrated CNS including LDACS, SATCOM, and ATN-IPS — directly aligned with their core ATN expertise.
• PJ13-W2 ERICA
  Represents their expansion into RPAS/drone integration in controlled airspace, a high-growth area that extends their ATM expertise into unmanned aviation.
