What is new?
Airbus UpNext, a wholly-owned subsidiary of Airbus, has initiated the SpaceRAN (Space Radio Access Network) demonstrator. The project’s mission is to test the feasibility of providing universal, standardized, and interoperable connectivity compatible with commercial, defense, and governmental applications.
The initiative seeks to offer a secure and cost-effective way for customers to remain connected in an increasingly digitized world.
Key Technology
The SpaceRAN demonstrator will utilize Airbus’s software-defined satellite technology, which allows satellites to be reprogrammed from the ground after launch. The system is designed to process 5G signals and data directly in orbit, rather than simply relaying them back to Earth. This in-orbit processing is expected to reduce latency, maximize data throughput, and enable more efficient network management, including direct user-to-user connectivity.
The collaboration will support two primary test platforms: a comprehensive on-ground test bed to simulate Low Earth Orbit (LEO) satellite behavior and an in-orbit payload on an Airbus LEO satellite. This payload will function as a 5G non-terrestrial base station, connecting aircraft and users on the ground.
Potential Impact and Timeline
Successful exploration of this technology could provide significant advantages across multiple sectors. For commercial aviation, it may enhance operational efficiency and improve passenger connectivity experiences. For military and government users, the project aims to deliver more resilient and secure communications, supporting better situational awareness and faster decision-making.
Developed as part of the Air!5G project, the demonstrator is supported by the French government through the France 2030 investment plan. First results are expected by 2028, with the findings intended to prepare for the next generation of wireless technology (6G).
Project Partners
To realize the initiative, Airbus has assembled a consortium of partners. The group includes Aalyria, AccelerComm, CesiumAstro, Deutsche Telekom, Eutelsat, the Industrial Technology Research Institute (ITRI), Keysight Technologies, Onati, Radisys, Sener, and ST Engineering iDirect.
