Back in early February this year, the Santih Computing Constellation undertook a three-satellite collaborative on-orbit intelligent processing experiment focused on water environment monitoring. Leveraging a surface feature extraction model, it successfully pinpointed crucial water bodies amidst ice formation. This process served to validate the constellation's full-link capabilities, encompassing satellite payload operation, on-orbit data processing, inter-satellite collaborative transmission, on-orbit model computation, and the transmission of task results. On February 12, the Santih Computing Constellation marked a significant milestone in inter-satellite networking. It accomplished the deployment and validation of 10 artificial intelligence models and applications. This achievement paves the way for innovative space computing applications in diverse scenarios, including deep space exploration and smart city construction. Notably, the constellation's inaugural batch of 12 computing satellites smoothly entered orbit on May 14, 2025. With a combined on-orbit computing power of 5 POPS, it has established itself as the world's largest space computing constellation in terms of computational capacity.
