| Oriental Tiansuan–Lightstandard Photonic Computing Satellite Program上海东方天算科技有限公司 | 光本位智能科技（上海）有限公司 | Supplier | Compute & storage · Processors / accelerators · Flight / payload software Joint space photonic-computing payload development: Lightstandard provides photonic chip architecture, the compute engine and software support; Oriental Tiansuan leads payload engineering and integration, radiation… Details & project milestonesJoint space photonic-computing payload development: Lightstandard provides photonic chip architecture, the compute engine and software support; Oriental Tiansuan leads payload engineering and integration, radiation hardening, thermal management, power adaptation and orbital environmental verification. SEMI attributes the announcement to Oriental Tiansuan. This supports a development collaboration, not a flown payload, a disclosed procurement contract or tested computing capacity. Buyer, price and exact flight schedule remain unknown. A 16 May Jiefang Daily / Shangguan News report specifies this workshare and a 300 TOPS per-card rating without identifying its precision; orbital environmental verification was forthcoming. This does not establish a flown payload, direct procurement buyer or value. Evidence: https://finance.sina.com.cn/jjxw/2026-05-16/doc-inhxzvnw2751178.shtml Disclosed buyer: Not disclosed. Associated organization: 上海东方天算科技有限公司. Oriental Tiansuan–Lightstandard Photonic Computing Satellite Program: Joint development announced Next project milestone: Identify the flight spacecraft and verification/launch schedule; publish rating precision, power requirements and independent in-orbit results This is a project target, not a supplier delivery commitment.

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.
