NAV CANADA is selling its long-held stake in the real-time, global air traffic surveillance and aviation data tracking company Aireon LLC. Iridium Communications is acquiring the remaining 61 percent stake in the space-based air traffic surveillance provider for approximately US$366.7 million, with NAV CANADA receiving US$166 million for its shares.
The transaction transitions Aireon from a multi-national joint venture into a wholly owned subsidiary of Iridium.
NAV CANADA played a pivotal role in bootstrapping Aireon’s technology in 2012, committing an initial investment of up to US$150 million to host Automatic Dependent Surveillance-Broadcast (ADS-B) receivers on the Iridium NEXT satellite constellation. Following early validation flights over Canadian airspace in 2017, the system became fully operational in 2019. This enabled NAV CANADA to reduce aircraft separation standards and increase flight routing efficiency across the heavily trafficked North Atlantic Tracks.
The decision to sell in 2026 aligns with NAV CANADA’s current fiscal requirements. As a not-for-profit utility, the organization has recently navigated elevated capital expenditures for core physical infrastructure and staffing, reporting a negative free cash flow of $71 million CAD in the second quarter of fiscal 2026. The US $166 million divestiture provides a strategic injection of capital to support these domestic air traffic control operations.
“This decision aligns with our continued focus on our core services and our strategic direction, ensuring we deliver the greatest value to our customers and stakeholders,” stated Micheline Pion, Vice President and Chief Financial Officer of NAV CANADA. “Having achieved our strategic objectives of establishing space-based surveillance capabilities and helping to grow Aireon’s business into a robust provider of data used by NAV CANADA, we are now poised to enter into the next phase of our commercial relationship with Aireon”.
While relinquishing its equity, NAV CANADA has secured its operational reliance on the system. The agency signed an extended data services agreement, guaranteeing uninterrupted access to Aireon’s surveillance telemetry through at least 2035.
For Iridium, consolidating ownership eliminates minority interests and sets the stage for the next phase of aviation data infrastructure. The company intends to leverage its fully integrated platform to advance space-based VHF communications. Once deployed, this technology is designed to allow air traffic controllers to communicate directly with pilots over oceanic and remote regions using standard 117.975–137 MHz VHF radios, requiring no new avionics or flight deck modifications.
The transaction is expected to close in the summer of 2026, with the purchase price for NAV CANADA’s shares payable in two equal tranches at closing and on the one-year anniversary
