Compute hardware: proFPGA motherboard with Xilinx Zynq UltraScale+ ZU19EG, quad-core Cortex-A53 and dual-core Cortex-R5 Historical ground SAR breadboard, not flight hardware. Section 2 identifies the ground breadboard used for the SAR processing module. This is a prototype configuration designed for onboard processing, not hardware demonstrated in orbit. primary research ground prototype. Included with these qualifications. Source observation: 2026-10-28. Supporting source ↗Memory / storage: 4 GB Historical ground SAR breadboard, not flight hardware. Section 2 reports DDR4 SDRAM on the processing-system side of the ground breadboard. Separate from programmable-logic memory and flash storage. This is not orbital capacity. primary research ground prototype. Included with these qualifications. Source observation: 2026-10-28. Supporting source ↗Memory / storage: 5 GB Historical ground SAR breadboard, not flight hardware. Section 2 reports DDR4 SDRAM attached to the programmable-logic side of the ground breadboard. Section 3 links this limit to processing one 8k by 32k raw-data block. Separate from processing-system memory, not an additional spacecraft or service capacity. primary research ground prototype.

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.
