With the rapid advancement of CubeSat and AI technologies, the integration of real-time AI image recognition with spectral analysis has opened up new application opportunities for small satellites. This study proposes a 1U CubeSat system that combines an embedded AI module with a miniature hyperspectral spectrometer, enabling on-orbit real-time image classification, anomaly detection, and cloud cover labeling. This approach effectively enhances the value of satellite imagery and reduces data transmission requirements.
By comparing onboard observations with real ground data, the system quickly identifies anomalous regions and downloads corresponding RGB and hyperspectral images to support timely assessment of environmental changes and the development of response strategies on the ground. The system provides five primary classification labels—clouds, water, ice, buildings, and land. In particular, cloud coverage can be analyzed in real time at different levels of obscuration, and images deemed overly cloud-covered are automatically excluded to avoid transmitting unnecessary data. Achieving efficient image classification under low power consumption and effectively overcoming AI computing constraints in a 1U CubeSat platform.
