Summary of Key Points
In July 2026, Shanghai officially launched the "Xingshu Plan," with its first constellation being a major initiative focused on developing space-based computing capabilities. The goal is to establish an integrated intelligent computing network that spans both Earth and space. This initial constellation adopts a "one main, two auxiliary" satellite configuration (one central computing satellite + Fuxi weather satellite + real-time remote sensing satellite), enabling data processing in orbit (without the need to transmit it back to Earth). Additional satellites will be launched in phases over time. The project is led by Fudan University in collaboration with enterprises, supported by a team of academicians, and aims to provide not only space computing capabilities for rental but also intelligent services. It is expected to drive the Shanghai space computing industry to generate an annual output value of over 100 billion yuan, contributing to the country's aerospace strategy and the Belt and Road Initiative.
Detailed Analysis
1. What exactly is the Xingshu Plan?
In simple terms, the Xingshu Plan is a "super project" aimed at building a space-based computing cluster in Shanghai. It involves a constellation of multiple satellites divided into three phases:
- Verification Phase: Launch of 2 computing satellites and 12 edge computing satellites as a preliminary test.
- Commercial Phase: Launch of 50 computing satellites and 100 edge satellites to start generating revenue.
- Operation Phase: Deployment of thousands of satellites to achieve full coverage.
The project is led by Fudan University (responsible for technology) and Shanghai Xingshu Tian Su Company (responsible for operations), with the support of four academicians serving as chief scientists, ensuring the success of the initiative.
This plan has ambitious goals: to become China's first space computing infrastructure, allowing satellites in orbit to collect data (such as weather and ground images) and process it directly in space using AI, thereby eliminating the need to transmit massive amounts of raw data back to Earth, which saves time and costs.
2. How does the "one main, two auxiliary" constellation work?
The three initial satellites form the smallest closed-loop computing unit, functioning like a mini-workstation in space with each satellite having a specific role:
- Central Main Satellite (Space Brain): Responsible for command and computation. It serves as the core of the constellation, receiving data from the other two satellites, analyzing it using AI models, and providing on-demand computing services.
- Fuxi Weather Satellite: Specialized in weather monitoring. Equipped with high-precision instruments, it can collect global atmospheric temperature, humidity, and cloud distribution data 24/7. It uses advanced models to provide faster and more accurate weather forecasts, aiding in the early detection of extreme weather events.
- Real-Time Remote Sensing Satellite: Used for capturing ground images. With high-resolution visible and infrared cameras, it can quickly photograph cities, farmland, and coastlines, and analyze the data in space to provide immediate results for emergency response and natural resources management departments.
The remarkable feature is that these satellites are connected by laser links, allowing all data collection and analysis to occur in orbit, eliminating the need for data transmission back to Earth. This is similar to using a smartphone to take and edit photos directly on the device, without the need for a computer.
3. Advanced Technologies
The central main satellite features five domestically developed innovations that fill critical gaps in space technology:
- Domestically Made Aerospace GPU: Equipped with a custom-made space-grade GPU chip capable of 32 PFLOPS of computing power (32 trillion operations per second), solving the issue of slow satellite computations.
- In-Orbit Large Models and Intelligent Maintenance: The satellite can self-repair its GPU modules in space and test cutting-edge technologies like microwave vision, which are not affected by weather conditions.
- Perovskite Solar Power Generation: Uses perovskite solar panels to generate 15 KW of power, more efficiently than traditional silicon panels while being cheaper than gallium arsenide panels, addressing the issue of high power consumption in space.
- Three-Level Cooling System: Combines liquid cooling, thermal insulation materials, and radiators to prevent the GPU from overheating, representing the first stable cooling solution for space-grade GPUs (where there is no air).
- 400Gbps Laser Communication: Enables fast data transmission between satellites and Earth at 400 Gbps, ensuring efficient interconnectivity of computing resources.
4. Practical Benefits
This project offers practical benefits:
- Cost Reduction for Enterprises: Companies that require large amounts of computing power (e.g., for AI training or spatiotemporal data processing) can rent space-based computing resources, saving money and time.
- Immediate Services: Advanced weather forecasting and disaster response capabilities, such as real-time analysis by the Fuxi satellite, which significantly speeds up emergency responses.
- Economic Growth: It is expected to drive the development of thousands of related enterprises in Shanghai, generating an annual output value of over 100 billion yuan, creating more jobs and opportunities for innovation, making Shanghai a leader in space computing.
5. Strategic Value
The Xingshu Plan has broader implications:
- National Aerospace Strategy: Helps build an integrated computing infrastructure that fills a gap in China's space computing capabilities and supports its leadership in the field of aerospace AI.
- Belt and Road Initiative Services: Provides meteorological and remote sensing services to partner countries, enhancing China's international influence by aiding in disaster prevention and ecological monitoring.
- Talent Attraction: Draws top talents in aerospace and AI fields, making Shanghai a hub for space computing expertise.
In summary, the Xingshu Plan represents a significant milestone for Shanghai in the field of space computing. With its advanced technology and economic benefits, it not only enhances China's aerospace capabilities but also contributes to national development. In the future, we may see these space satellites playing a crucial role in various everyday services, such as weather forecasting and disaster response.
