Regenerative NTN architecture moves the 5G base station function into the satellite itself. Rather than bending signals back to ground for processing, the payload handles Layer 1 and above onboard — enabling lower latency, reduced ground infrastructure dependency, and greater network resilience. It is also one of the most demanding environments any physical layer IP will ever encounter.
Onboard processing places every constraint of a satellite payload — power, thermal, radiation, mass — directly onto the PHY. Software-based Layer 1 implementations cannot deliver the throughput and efficiency that commercial regenerative constellations require within those constraints. Hardware-accelerated IP is the only viable path to performance at scale.
AccelerComm's AX-RG provides complete 5G NR Layer 1 acceleration for regenerative satellite payloads, built on flight-proven LDPC and signal processing IP already deployed in orbit on more than 100 commercial satellites. For constellation programmes where the physical layer is a critical path item, AX-RG provides a validated, standards-based foundation that de-risks payload development from the outset.
