A team from the Space-based Intelligence Laboratory at the Innovation Academy for Microsatellites of the Chinese Academy of Sciences has published a detailed review of orbital edge computing (OEC), examining system design, applications, algorithms, and supporting tools. Their survey highlights current capabilities, major challenges, and future research directions for this rapidly advancing technology.

OEC enables satellites to process data directly in orbit rather than transmitting raw information back to Earth. This approach reduces latency, alleviates bandwidth limits, and allows real-time services such as augmented and virtual reality, high-resolution video streaming, and Earth observation. It also supports federated learning across constellations, enabling collaborative AI training wh
