The core digital engine of NantNova's optical communication terminals, implementing SDA-compliant LDPC forward error correction at 2.5 Gbps using OOK-NRZ modulation.
Constellation operators need optical crosslinks that interoperate on day one — across vendors, protocols, and orbital regimes. The DPU is the processing core that makes that possible. It handles LDPC encoding, multi-protocol routing, and real-time error correction at 2.5 Gbps, so every SatLight™ terminal ships SDA-compliant and ready to close links from 1,000 to 6,000 km without integration surprises.
Built on FPGA today with an ASIC tape-out on the roadmap, the DPU is designed from the start for the DARPA Space-BACN cost and power targets. It speaks every waveform standard that matters — SDA 2.0/3.0/4.0, OISL, CCSDS, and NASA Optical — so your constellation isn’t locked into a single protocol generation. One processing unit, every standard, proven BER performance.
The DPU implements SDA-compliant LDPC forward error correction at 2.5 Gbps using OOK-NRZ modulation. It handles encoding, error correction, and multi-protocol routing — enabling interoperable crosslinks across LEO constellations from 1,000 to 6,000 km.
The architecture scales from current 2.5G implementations to future high-rate configurations using 3GPP 5G NR LDPC coding, with a clear path from FPGA to ASIC for volume production.
