Compute hardware: Five Raspberry Pi 5 boards with quad-core Arm Cortex-A76 processors Five-node Raspberry Pi 5 ground research cluster. Section 10.4 and the results tables identify the evaluated five-board cluster. An earlier development paragraph mentions one controller and three workers. The configurations are not combined, and none is flight hardware. published ground research testbench. Included with these qualifications. Source observation: 2026-10-28. Supporting source ↗Memory / storage: 8 GB RAM per Raspberry Pi 5 board Five-node Raspberry Pi 5 ground research cluster. Ground-cluster memory per board from the paper.

Compute hardware: Kalray-equipped AMD64 host, NXP LX2160 16-core Arm node and Versal VCK190 node Three-node heterogeneous ground research cluster. Mixed-architecture ground testbench identified in section 10.6. Its lab-network links, CPU counts and memory are not a deployed orbital constellation or a spacecraft link specification. published ground research testbench. Included with these qualifications. Source observation: 2026-10-28. Supporting source ↗Memory / storage: No supported value is assigned to this configuration. The recorded coverage note applies to another configuration. | ||
Technical specifications retain the source’s original units and evidence status. Hardware counts, compute rates and power are not equivalent; launched hardware does not establish demonstrated performance. Supplier counts include suppliers and hosts only, reflect current filters and cover this directory, not the entire market. “No record” means no disclosure captured; it does not mean the work is unawarded. Latest developments use source dates, not routine review or collection dates.
