Efficiency analysis and reconfiguration control method of small satellite remote sensing formation constellation

The effectiveness and reconfiguration analysis of Leo large-scale remote sensing satellite constellation is of great significance to satellite constellation system design and system maintenance. This article first analyzed the performance of the latest remote sensing satellite constellation through comprehensive index evaluation function. Then the feature of on-orbit service failure was analyzed according to the service availability of life prediction model. The residual properties of constellation in different failure modes was also introduced and the optimization strategy for the rest of the constellation to reconfiguration was optimized. Finally, the reconfiguration path was reconstructed by the optimal control method and LQR control strategy was used to the simulation, which can assess the overall performance of the constellation in the process of damage and reconstruction and the rationality of the reconfiguration scheme.
