At the beginning of 2026, space computing power, as the core track to break through the bottleneck of ground computing power supply and support the high-quality development of the digital economy, is entering a critical window period of global competition and technological breakthroughs. Recently, the high computing power payload developed by Spatiotemporal Daoyu has successfully completed full dimensional in orbit technology verification and obtained authoritative certification from the Theil Report, marking a major breakthrough in China's construction of on-board computing power system. This has laid the core technology foundation for the large-scale deployment of integrated computing power network in space and space, and also demonstrated the leading competitiveness of Spatiotemporal Daoyu in the global space computing power track.
First in orbit operation of DeepSeek big model and sky earth diagnostic application
As the core pillar of the space computing power layout in space-time, the development and in orbit verification of high computing power payloads have always focused on the three core goals of "efficient computing power, balanced energy efficiency, and scene adaptation", and have achieved full chain autonomous controllability after years of technological research and development. As early as September 2025, the Beida Space Time Star 01 test satellite carrying this high computing power payload was successfully launched into orbit in the waters near Rizhao, Shandong. It has achieved long-term stable operation in orbit and successfully completed the in orbit verification of onboard computing power technology.
The satellite is based on industrial grade devices to achieve high computing power in orbit, and for the first time, it has operated the DeepSeek large model and the application of space and earth diagnostics in orbit. It has completed in orbit verification in conjunction with advanced satellite communication technology, providing key technical support for subsequent emergency communication, remote medical care, and space-based universal computing services. This is also an important practice for the joint efforts of space-time, aerospace, and universities to deepen industry university research collaboration and promote the landing of core space computing technologies.
High computing power and low power consumption, empowering diversified intelligent applications
The high computing power payload completed in orbit verification this time has built a satellite computing power platform that combines elastic expansion and multi scenario intelligent application capabilities. The core technical indicators meet the design requirements. This platform strictly controls the overall power consumption at an extremely low level while meeting the high computing power requirements, successfully achieving the optimal balance between computing power and energy efficiency in extreme spatial environments, and solving the industry pain points of "insufficient computing power and high power consumption" in traditional spaceborne devices. Of particular note is that the payload integrates core capabilities such as onboard mobile models and high-precision image processing inference models, which can efficiently support diverse intelligent application scenarios such as real-time dialogue for assisted diagnosis and object/vehicle/license plate recognition (accuracy ≥ 95%). The response speed of the onboard language model fully meets the real-time interaction requirements of space scenes.
At the level of system architecture and data interaction, this high computing power payload innovation adopts an AI operating system and is equipped with a dedicated application proxy module. It not only achieves fine control and full process visualization operation and maintenance of the on-board computing power platform, but also connects the key links of efficient interaction and protocol conversion of satellite ground data, solving the core problems of high latency and poor compatibility in space and ground data transmission. At the same time, the platform supports active remote update of large model knowledge base, which can be upgraded according to application scenario iteration and business requirements, optimize model capabilities in real time, and ensure the continuity and progressiveness of on-board computing services.
Resist radiation damage and ensure long-term in orbit service
In the field of radiation resistance, satellite platforms focus on ensuring the stability of equipment in orbit and the full life cycle of computing systems. Through core technology optimization, they can effectively resist the erosion and loss of hardware caused by strong radiation environments in space, ensuring the achievement of the preset service life. The core direction of its technological research and development is to improve the reliability of space equipment in orbit and extend its service life. It can not only build a strong protective barrier for the long-term stable operation of high computing power payloads on spacecraft, but also effectively reduce the interference of space radiation on computing power platforms, strictly control the data error rate of in orbit operation at an extremely low level, and fully meet the strict requirements of large-scale applications of satellite computing power.
The successful completion of this long-term in orbit verification not only fully verifies the reliability, stability, and adaptability of the on-board high computing power platform, but also marks the formation of a full chain core capability in space computing hardware deployment, software architecture construction, and intelligent application landing by Spatiotemporal Universe, becoming one of the few domestic technology enterprises with end-to-end solutions for on-board computing power. It is understood that the authoritative certification of the Thiel report further proves the core advantages of the high computing power load in terms of technical progressiveness, performance stability, etc., and provides an important cornerstone for its subsequent commercial application and large-scale deployment.
Industry experts point out that currently, space computing power has become a strategic high ground for global technological competition, and it is also the core engine for breaking through the bottleneck of ground computing power and supporting the high-quality development of the digital economy. It is entering a critical period of transition from conceptual exploration to industrialization. As the core pillar of the strategic layout of space computing power in space-time, high computing power payloads have successfully built an integrated technology base of 'in orbit computing+space earth interconnection' through in orbit verification, providing an irreplaceable core technical guarantee for the paradigm shift of space computing power from 'day earth calculation' to 'day sky calculation', and helping China seize development opportunities in the global space computing power track. ”
The layout and in orbit verification of high computing power payloads and platforms are all thanks to the technological and industrial layout of Space Time Aerospace in the commercial aerospace field. Currently, the first phase of the low orbit satellite IoT constellation with 64 satellites has been deployed, relying on full stack self-developed capabilities and satellite super factory mass production capabilities, providing efficient engineering support for the landing of core technologies.
Against the backdrop of the explosive growth in global demand for AI computing power and the mainstream paradigm of industrial upgrading in space-based computing, the successful in orbit verification of high computing power payloads in space-time will effectively promote the transformation of space data from "ground processing" to "real-time processing in orbit", greatly improving the utilization efficiency and value transformation ability of space data, and providing a new computing power support paradigm for emergency rescue, smart transportation, remote medical and other fields.
