According to the future space technology development trends, the future spacecraft DIY idea and system standard are proposed. The standardized, modularized and serialized micro/nano-satellite DIY products are introduced. Finally, a commercial remote sensing satellite system based on spacecraft DIY is designed and its application prospect is analyzed.展开更多
