Space-Based Aircraft Surveillance System Gains Single Owner in $366.7M Deal
Acquisition Unifies Aireon’s ADS-B Network With Iridium Satellite Constellation, Extending Key Partnerships Through 2035
A deal announced Thursday would place the world’s only space-based air traffic surveillance system under the full ownership of the satellite company that carries it, folding Aireon LLC into Iridium Communications Inc.
“The aviation industry is now entering an era of growing air traffic, denser airspace, autonomous aircraft and greater expectations for safety and resiliency.”

Iridium, already a partial owner of Aireon, signed a definitive agreement to acquire the remaining 61% of Aireon’s equity interests for approximately $366.7 million from the system’s other shareholders: NAV CANADA, AirNav Ireland, ENAV of Italy, NATS of the United Kingdom, and Naviair of Denmark. The transaction is targeted to close in early July, subject to regulatory approvals.
“Aireon has always been part of Iridium’s aviation safety strategy,” said Matt Desch, CEO of Iridium. “We founded it in partnership with the world’s leading air navigation service providers, because we believed space-based aviation safety was a generational opportunity. The aviation industry is now entering an era of growing air traffic, denser airspace, autonomous aircraft and greater expectations for safety and resiliency. Bringing Aireon fully inside Iridium better positions us to build what’s needed to support the future of aviation, including more innovations like the future introduction of space-based VHF communications.”
The Aireon system, certified by the European Union Aviation Safety Agency, flies as a payload on the Iridium satellite constellation and tracks an average of 190,000 flights per day. Commercial aircraft equipped with Automatic Dependent Surveillance-Broadcast, or ADS-B, transponders broadcast their identity, location, altitude, speed and heading — data Aireon captures in real time with 100% global coverage, including oceans, polar regions and remote areas where ground-based radar cannot reach. Air navigation service providers covering more than 50% of global airspace rely on that data.
The combined company would deliver four capabilities on one platform: global aircraft tracking, pilot-to-controller satellite communications, positioning, navigation and timing integrity services, and aviation data analytics. Iridium says no other satellite operator offers all four globally.
As part of the deal, NAV CANADA and NATS — which together manage the North Atlantic Tracks, the most heavily trafficked oceanic airspace between Europe and North America — will sign extended data services agreements through 2035 and beyond, with provisions for cooperative development of space-based VHF communications.
“NAV CANADA is proud of our foundational role in establishing Aireon’s world-first technology,” said Mark Cooper, president and CEO of NAV CANADA. “This sale sharpens our focus on our core expertise: keeping Canada’s skies safe. As a fellow founding partner, Iridium is the ideal owner to guide Aireon’s continued commercial growth.”
“We have been proud to be a part of Aireon’s successes, most notably making real-time aircraft surveillance over the Atlantic a reality for the first time in history,” said Martin Rolfe, CEO of NATS. “As a shareholder for the past eight years, it is now the right time for us to divest. We are confident Aireon is well positioned for the future.”
Beyond surveillance services, Aireon operates a growing aviation data business selling real-time and historical data to airlines, airports, manufacturers, governments and aerospace operators. Products available or launching this year include turbulence detection, GPS jamming and spoofing detection, and safety and efficiency analytics.
“Becoming part of Iridium is a natural next step for our team, our customers and our roadmap, particularly as our data products expand into new areas like turbulence detection and aviation data analytics,” said Don Thoma, CEO of Aireon. “Together, we are building the foundation for the future of global aviation.”
Aireon will continue normal operations in the near term with no planned changes to business strategy.
Aireon’s total revenue has grown at a compound annual growth rate of 10% over the past three years. Iridium expects the acquisition to contribute at least an additional $100 million in annual service revenue and $30 million in annual operating earnings on a consolidated basis.
The $366.7 million purchase price will be paid 50% in cash at closing and 50% one year later, structured as an interest-free seller loan secured by a first-priority lien on Aireon’s equity. Iridium will also assume Aireon’s outstanding debt, expected to be approximately $155 million at closing, funded through existing liquidity and its revolving credit facility. Net leverage is expected to reach approximately 4.0 times operating earnings in the third quarter of 2026 before returning to current levels within 12 months, with a long-term target of 2.0 times by the end of the decade.
