If you’re traveling during the holiday season, then you’ll likely be anticipating the dreaded packed airports and flight delays. There may soon be a reason to rejoice, however, as a space-based system could be taking over air-traffic communications in the near future with promises for better efficiency.
The European Space Agency (ESA) announced a collaboration with Boeing and satellite operator Viasat to test an emerging space-based technology that connects pilots with air traffic controllers using satellites. A series of test flights took place in late October and early November to and from different parts of the United States and Europe, according to ESA. Tests of the system began last year in Europe, but the technology is now going global.

Traditionally, pilots communicate with air traffic control using ground-based radio systems, broadcasting data on their position to ground stations. Space-based air-traffic control moves some of these functions to orbiting satellites, receiving signals from aircraft through space instead of stations on Earth. This allows for more accuracy and efficiency as it relays near real-time updates. It also improves accuracy for routing and spacing between aircraft due to more frequent reporting of their positions.
Boeing recently conducted a series of test flights using the satellite-based Iris system on a United Airlines aircraft. The aircraft is part of Boeing’s ecoDemonstrator program, which tests different technologies with the aim of making commercial flights more sustainable and efficient.
Iris, which is developed by Viasat in partnership with ESA, has been operational in Europe since 2024 and used on more than 17,000 flights so far, according to the space agency.
“This partnership marks a crucial milestone towards a unified global solution for Air Traffic Management. Through this testing of interconnected digital communications, we are not only advancing operational efficiency but also moving towards safer and more efficient airspace,” Laurent Jaffart, ESA director for Connectivity and Secure Communications, said in a statement. “Ultimately, this will deliver significant economic benefits and help reduce emissions, supporting the aviation industry in achieving its sustainability goals.”
Iris provides secure communications between pilots, air traffic controllers, and airline operation centers. The system relies on Viasat’s existing infrastructure of 14 satellites placed in geostationary orbit, providing coverage across Europe with the potential to expand globally. The goal is to create more efficient flight routes in order to reduce CO2 emissions and flight delays for passengers.
