Oriental Tiansuan–Lightstandard Photonic Computing Satellite Program
This project focuses on developing photonic computing for use in orbit.
Oriental Tiansuan and Lightstandard announced a space photonic-computing collaboration in May 2026. A subsequent report describes their jointly developed payload as rated at 300 TOPS per card, with INT8/FP8/FP16 support but unspecified rating precision. Lightstandard supplies the photonic compute architecture, engine and software; Oriental Tiansuan leads payload engineering and space qualification. Orbital validation remains unverified; no named launched spacecraft or procurement value is established.

300 TOPSPlannedOne photonic-electronic computing card in the jointly developed payload intended for orbital validationEvidence & scope
Official Shanghai Science and Technology Commission report gives a 300 TOPS per-card design rating and INT8, FP8 and FP16 support. It does not assign the rating to one precision, disclose card count or establish measured orbital throughput.
Figures retain their disclosed units and scope. Launched hardware does not establish demonstrated performance; targets may change. Not disclosed means no figure in the reviewed sources.
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 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

Identify the flight spacecraft and verification/launch schedule; publish rating precision, power requirements and independent in-orbit results
Manual review 29 Oct 2026. Direct review of Oriental Tiansuan, Shanghai government and Lightstandard materials confirmed a planned photonic-electronic orbital-validation card rated at 300 TOPS with INT8, FP8 and FP16 support. Precision basis, card count, IT power, launch assignment and measured orbital performance remain undisclosed. Primary body last observed 21 Oct, 13:13 UTC. Source monitoring: unavailable. Source collection and substantive profile review are separate checks. Plans and dates may change.

This Shanghai collaboration is distinct from BUPT's Tiansuan orbital research platform
Oriental Tiansuan later announced the separate Mingzhu constellation plan. The specific allocation of this Lightstandard photonic payload to named Mingzhu spacecraft remains unverified; the 300 TOPS card rating is not Mingzhu constellation capacity.
Project updates
Verified announcements and milestones linked to this project, newest first.
Jiefang Daily / Shangguan News reports the jointly developed payload at 300 TOPS per card with INT8/FP8/FP16 inference support; the rating precision is unstated. Orbital environmental verification remained forthcoming. This dates the publication, not a completed orbital test.
The company-attributed SEMI publication identifies Shanghai Oriental Tiansuan and Lightstandard, a joint innovation center and photonic payload development. It also describes an associated satellite-development effort; the publication date is used, with no invented signing or launch date.
