Compute throughput: 2 POPs · Arithmetic precision not specified Announced design compute of Fudan Optoelectronics-1, the ultra-low-orbit remote-sensing satellite in the initial Xingshu cluster. Fudan prints the native unit as 2POPs. Computational precision, operation type and sustained performance are not specified. This applies only to the remote-sensing satellite under development, not the central computing satellite or total constellation. No launched or demonstrated throughput is established; do not convert to PFLOPS. Planned specification. Included with these qualifications. Source observation: 2026-08-03. Supporting source ↗ | |
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.
