Aircraft Achieves 2.6 Gbps Laser Connection to Satellite 36,000 Kilometers Away
Delft, Tuesday, 3 March 2026.
European aerospace teams successfully transmitted data at 2.6 gigabits per second between a moving aircraft and a geostationary satellite positioned 36,000 kilometers above Earth. The breakthrough demonstration achieved zero bit errors during multiple test sessions, each lasting 6-14 minutes, proving that laser beams can maintain stable connections despite aircraft vibrations and atmospheric interference. This technology promises to revolutionize aviation communications by delivering internet speeds 1,000 times faster than current radio systems while providing enhanced security against jamming.
Photonics Technology Enables Ultra-Secure Communications
This achievement represents a significant advancement in photonics technology, which uses light particles (photons) to transmit information [GPT]. The UltraAir terminal, co-developed by Airbus and Dutch research organization TNO, demonstrated the practical application of optical communication systems in challenging aerospace environments [1][2]. The December 2025 test campaign achieved 31 successful links with closed loop tracking, each lasting 6-14 minutes, generating hours of telemetry data [1][2]. Seven specific tests transmitted data at 2.6 Gbps with zero bit errors, proving the system’s reliability under real-world conditions [1][2].
Technical Precision Overcomes Distance and Movement Challenges
François Lombard, Head of Connected Intelligence at Airbus Defence and Space, emphasized the technical complexity involved: “Establishing laser links between moving targets at this distance is technically very challenging. Continuous movements, platform vibrations and atmospheric disturbances require extreme precision” [1][2][3]. The system must maintain a precise laser beam connection across 36,000 kilometers while compensating for aircraft movement, vibrations, and atmospheric interference in real-time [1][2][3]. The tests were conducted using a Dassault Falcon 20 research aircraft flying from Nimes, southern France, connecting to the Alphasat TDP-1 satellite in geostationary orbit [3][4].
European Industry Leadership and Strategic Implications
The collaboration demonstrates European technological leadership in secure communications. Kees Buijsrogge, Director of Space at TNO, stated: “This breakthrough proves that European industry delivers technology with strategic global impact. Secure laser communication is essential for both defense operations and civil connectivity. By leading in this field, we are strengthening Europe’s security and its autonomy” [2][3]. TNO developed the optical, mechanical, and control technology, while Airbus leads the UltraAir project and integrates the terminal into aircraft [1][2]. The UltraAir project receives co-financing from Airbus, TNO, the Netherlands Space Office, and the German Aerospace Center [1][2].
Commercial Applications and Future Market Impact
The technology promises to revolutionize both military and civilian communications. Laser-based optical links can transfer terabytes in seconds, offering speeds potentially 1000 times faster than current radio frequency systems [4]. Harald Hauschildt, Head of ESA’s Optical and Quantum Communication Office, noted that “optical communications between airborne users and satellite networks, like ESA’s High-thRoughput Optical Network (HydRON), are high on ESA’s agenda” [3]. The system’s anti-jamming capabilities make it particularly valuable for defense applications, while commercial aviation could benefit from high-speed passenger internet services [4][5]. Beyond aviation, the technology could enable secure laser communication for ships, vehicles, and commercial high-speed internet in remote areas [1].
