摘要
The solar array (SA) is a vital component of satellite electrical power systems, providing a continuous energy supply for sustained on-orbit operations. Accurate identification of its operating modes, supported by multi-source sensing data, is essential for efficient satellite management. This study introduces a dual-branch spatial-temporal coding framework to address the limited recognition accuracy and weak dynamic perception of conventional data-driven methods. The key contribution lies in extracting complementary spatial and temporal features from sensing data and integrating them through a soft gating mechanism that adaptively fuses cross-modal information. To enhance reliability, temperature-scaled posterior probabilities are applied to calibrate model confidence, particularly during rapid transitions between dynamic operating modes. Experiments with on-orbit telemetry data show that the method achieves 99.49% accuracy, while the soft gating fusion reduces the expected calibration error by more than 21.4%. By combining multidimensional feature modeling, feature fusion, and confidence calibration, this study provides a robust and reliable solution for satellite SA operating mode identification.
