Shanghai's 'Xingshu Plan' adopts perovskite tandem solar cells for its first space computing satellite cluster

Xingshu Plan (星枢计划) is a Shanghai-based space computing program led by Fudan University, which supplies the underlying space-based large-model technology, together with Xingshu Tiansuan Aerospace Technology, which leads the program's research, development and operations. The program aims to build a distributed network of computing satellites that provide on-demand computing services to sectors including energy, maritime and government. During the recent World Artificial Intelligence Conference (WAIC) in Shanghai, the program unveiled its first "constellation" - a group of three linked satellites, launched together to work as a single coordinated unit. The group uses a "one main, two auxiliary" architecture: a central computing satellite, a "Fuxi" weather satellite carrying a microwave radiometer for all-weather atmospheric sensing, and an ultra-low-orbit remote-sensing satellite with its own onboard edge-computing capability. The three satellites are linked by inter-satellite laser communication, and the group is designed so that data collection, AI inference and analysis are all completed in orbit, without needing to downlink raw data to the ground. It's the central computing satellite in this first group that uses perovskite tandem solar cells to provide its power.
