Airbus has launched a new technology demonstrator designed to test global 5G connectivity directly from orbit. The project, known as Airbus UpNext SpaceRAN, is being developed by Airbus UpNext, a wholly owned subsidiary focused on exploring future aerospace technologies.
The SpaceRAN demonstrator is intended to explore 5G Non-Terrestrial Network (NTN) capabilities. These standards are designed to extend mobile network connectivity beyond ground-based infrastructure, using satellites as part of the radio access network. Airbus says the goal is to assess the feasibility of providing standardized, interoperable, and globally available connectivity for commercial, defense, and governmental applications.
Unlike traditional satellite systems that primarily relay signals back to Earth, SpaceRAN will test the use of software-defined satellite technology to process 5G signals directly in space. Airbus states that onboard processing allows data to be managed and routed in orbit, rather than being handled entirely by ground stations. According to the company, this approach is intended to reduce latency, increase data throughput, and improve network management.
The demonstrator will also explore user-to-user connectivity enabled by regenerative satellite payloads. Airbus notes that this configuration supports more direct communication links between connected assets, including terrestrial and airborne users.
Michael Augello, CEO of Airbus UpNext, said the project is expected to support multiple use cases. In commercial aviation, the technology is intended to support operational efficiency and interoperability. For military and government users, the focus is on secure and resilient communications to support situational awareness and real-time decision-making.
To carry out the program, Airbus has formed a consortium that includes Aalyria, AccelerComm, CesiumAstro, Deutsche Telekom, Eutelsat, the Industrial Technology Research Institute, Keysight Technologies, Onati, Radisys, Sener, and ST Engineering iDirect.
SpaceRAN is being developed as part of the Air!5G program, which is supported by the French government under the France 2030 investment plan and the Future Networks strategy. Airbus states that the demonstrator is expected to deliver initial results by 2028 and will also contribute to research activities related to future wireless systems.
