R&D Institution: BUPT, SpaceTY, etc.

 Main tasks:

To serve as an inter-satellite communication node for building an on-orbit experimental open-source platform of space-air-ground computing within the space computing constellation.

 Other tasks:

1. Supporting satellite-ground link IP calls, satellite-ground data transmission link measurement experiments, semantic image communication experiments, on-orbit operation of on-board lightweight core networks, WASM measurement experiments, cloud-native satellite verification, on-board container dynamic updates, model robustness compression experiments, on-orbit incremental updates of classification models, on-board retrieval model inference, and single-event upset verification in low-orbit environments.

2. Supporting Peking University's evaluation of location privacy protection performance in on-board cellular networks, Tsinghua University's inter-satellite and satellite-ground data collaboration based on the IoT database IoTDB, Shandong University's verification of inter-satellite consensus algorithms, Yantai University's verification of ubiquitous sensing task allocation algorithms, ZTE's on-orbit service verification of on-board core networks, and the on-orbit deployment and experiments of multispectral cameras.

 Objective:

As the sixth satellite of the space computing constellation, it promotes the construction of an inter-satellite communication network.

 Contributions:

It establishes high-speed inter-satellite communication, lays the foundation for building an open-source platform for space-air-ground computing, and provides forward-looking technical support for China's intelligent digital infrastructure, 6G networks, and satellite internet.

  Highlights:

It realizes high-bandwidth laser communication between satellites and overcomes the core bottlenecks of traditional microwave communication in terms of bandwidth, delay, and security. It is like building an "optical fiber network" in space, establishing ultra-high-speed, high-security, and low-latency inter-satellite data links, enabling the real-time transmission of global massive data between satellites, and serving as the cornerstone for building a space-based information superhighway.

 Next plan:

Promote the construction of cloud-native ground stations and research an independently controllable open-source satellite platform integrating software and hardware.
