The European Space Agency has tapped AccelerComm to lead the physical-layer development for the D2SAT project. This research-stage initiative aims to deploy regenerative 5G gNodeB base stations directly onto low-Earth orbit satellites.
Why it matters
The project aims to validate regenerative processing to improve connectivity in space-based networks. By moving processing power on-orbit, the ESA targets significant efficiency gains in link budgets and hardware constraints.
The architecture utilizes a field-programmable gate array (FPGA) to accelerate physical-layer functions, targeting a 25 percent improvement in link budget and a 50 percent reduction in power and physical size. Dynamic resource allocation is expected to contribute a further 30 percent boost to the link budget.
The players
European Space Agency
An intergovernmental organization dedicated to the exploration of space and the advancement of satellite communication technologies.
AccelerComm
A Southampton-based firm specializing in physical-layer acceleration technology for 5G and satellite networks.
Antwerp Space
A Belgian aerospace company that leads the D2SAT consortium and specializes in satellite instrumentation.
The details
The project focuses on a regenerative 5G NTN (non-terrestrial network) gNodeB, a radio access network base station that processes data directly on a LEO (low-Earth orbit) satellite. The system incorporates beam steering—the precise directing of signal beams—and beam hopping to manage multiple users simultaneously. By using an FPGA, a type of integrated circuit designed to be configured after manufacturing, the team aims to handle complex physical-layer processing tasks on hardware that must meet stringent power constraints.
Timeline
The D2SAT development project is scheduled to last 26 months.
The Tech Race
The D2SAT project aims to reach Technology Readiness Level 5, marking a transition from laboratory validation to prototype demonstration in relevant environments. It competes with other industry efforts to optimize regenerative satellite architectures for the growing 5G NTN market.
This development is currently in the research phase and will not immediately reach end users. When implemented, this technology aims to increase satellite link efficiency, potentially enabling more reliable 5G connections for remote areas currently underserved by terrestrial infrastructure.
The takeaway
The ESA's focus on regenerative processing reflects a shift toward moving heavy computation from ground stations to space, aiming to lower power footprints by 50 percent. Observers should track the project's progress toward the TRL 5 milestone, which will signal the viability of this architecture for future satellite constellation launches.
