| Description |
The Beiyou-1 satellite is equipped with the “Tiansu Constellation” distributed intelligent computing platform jointly developed by the team of Professor Wang Shangguang of Beijing University of Posts and Telecommunications and Tianyi Research Institute.
Beiyou No. 1 satellite adopts the third-generation high-reliability integrated electronics platform of 天仪研究院, which can achieve a design life of 3-5 years according to redundant configuration, attitude control pointing The highest accuracy is 0.01°, and the main performance indicators are superior to similar international satellite platforms. It can be used as a long-term stable and reliable on-orbit test platform to provide universities, scientific research institutes and commercial enterprises with extremely cost-effective on-orbit science and technology verification services.
As the first main star of the “Tiansu Constellation”, its main task will be used to build the core nodes and test tasks of the “Tiansu Constellation” open source platform for aerospace computing on-orbit testing. The planned on-orbit deployment and development include: Distributed Spaceborne AI reasoning, spaceborne 5G core network V4, eBPF-based lightweight network elements, satellite-ground link reliability testing, spaceborne network protocol proxy, real-time video streaming, satellite-ground link transmission performance measurement, satellite-ground collaboration Time-series data management technology, low-orbit satellite encrypted channel data transmission technology, multi-space crowd sensing task allocation technology, and “satellite-ground” link adaptive transmission technology research, space-ground collaborative IP-optical fusion networking verification experiment, low Experimental verification of advanced technologies such as AI-based video streaming transmission and satellite application capability open platform in orbiting satellite scenarios.
In addition, the Beiyou-1 satellite is also equipped with a commercial camera lens module and two satellite payloads (GRID-07, GRID-08B) of the “Tiange Project” cooperation group.
The two “Tiange Project” satellite payloads carried this time are based on the technical solutions openly shared by Tsinghua University in the “Tiange Project” cooperation group. Among them, the GRID-07 payload was developed by Beijing Normal University, and the GRID-08B payload was developed by Nanjing University, Jointly developed by Sichuan University and completed by Tiange student teams from various schools, it is planned to carry out joint observations with the previously launched “Tiange Project” on-orbit payloads to detect gamma-ray bursts, solar activities, pulsars, etc. Conduct continuous on-orbit observation and analysis.
This is the 16th space mission of Tianyi Research Institute. So far, Tianyi has successfully launched a total of 26 satellites, including China’s first commercial SAR satellite “Haisi-1” and “Chaohu-1”. The trouble-free flight time in orbit exceeds 15,000 days.
Main tasks:
The core node of the open open source platform for aerospace computing in-orbit experiments of the Sky Computing Constellation.
Other tasks:
- Support distributed spaceborne AI inference test, spaceborne 5G core network V4 test, deployment of lightweight network element test based on eBPF, satellite-ground link reliability test, spaceborne network protocol agent, satellite-ground awareness transmission, real-time video streaming transmission, satellite-ground link transmission performance measurement, IP-optical fusion networking, and satellite application capability exposure.
- Support on-orbit deployment and experiments such as the No. 3 node of Peking University's data network, Tsinghua University's loTDB IoT database, Beihang University's lightweight container, Yantai University's multi-space crowd sensing, Hunan University of Science and Technology's distributed data security encrypted transmission, and Ascend AI's Atlas 200AI acceleration module.
Objective:
The first main star of the Tiansuan Constellation, promoting the construction of a satellite-ground collaborative computing platform.
Contributions:
It lays a technical foundation for the construction of an in-orbit open source test platform for aerospace computing, and provides technical support for China's construction of intelligent comprehensive digital infrastructure, 6G network and satellite Internet.
Highlights:
The application of cloud native technology system to satellites overcomes key technical challenges such as container weight reduction, satellite-ground network protocol compatibility, integration of spaceborne switching technology and satellite heterogeneous equipment management under power consumption and heat dissipation imbalance, so that Beiyou-1 satellite has the ability of payload service combination, which effectively solves the problems of incompatible traditional satellite payloads, difficult reuse of software and hardware, and slow technical iteration caused by difficulty in meeting the service diversity of users and the timeliness of experiments
Next plan:
Research on cloud-native satellites and technical systems that support inter-satellite links, and promote the construction of cloud-native ground stations.
