| Space Chord Computing Constellation (太空之弦)G1 per-satellite designSTAR.VISION / Oriental StarlinkProject status: Satellites launched | — | Up to 60 PFLOPS (FP8) · FP8 statedG1 per-satellite compute-payload design range upper endpointReported specificationProposed specification |
Compute throughput: Up to 60 PFLOPS (FP8) · FP8 stated G1 per-satellite compute-payload design range upper endpoint. Tidenews reports an approximate 40–60 PFLOPS FP8 range based on a reference configuration. This row stores the upper endpoint because the present metric schema has no range fields; neither endpoint is a tested or guaranteed capacity. Proposed specification. Included with these qualifications. Source observation: 2026-09-25. Supporting source ↗Compute hardware: No supported value is assigned to this configuration.

Compute throughput: Up to 310 PFLOPS (FP8) · FP8 stated G2 per-satellite compute-payload design range upper endpoint. Tidenews reports an approximate 160–310 PFLOPS FP8 range based on a reference configuration. This row stores the upper endpoint because the present metric schema has no range fields; neither endpoint is a tested or guaranteed capacity. Proposed specification. Included with these qualifications. Source observation: 2026-09-25. Supporting source ↗Compute hardware: No supported value is assigned to this configuration.

| Space Chord Computing Constellation (太空之弦)G3 per-satellite designSTAR.VISION / Oriental StarlinkProject status: Satellites launched | — | Up to 1,000 PFLOPS (FP8) · FP8 statedG3 per-satellite compute-payload design range upper endpointReported specificationProposed specification |
Compute throughput: Up to 1,000 PFLOPS (FP8) · FP8 stated G3 per-satellite compute-payload design range upper endpoint. Tidenews reports an approximate 460–1000 PFLOPS FP8 range based on a reference configuration. This row stores the upper endpoint because the present metric schema has no range fields; neither endpoint is a tested or guaranteed capacity. Proposed specification. Included with these qualifications. Source observation: 2026-09-25. Supporting source ↗Compute hardware: No supported value is assigned to this 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.
