Chinese Journal of Aeronautics 2018年第10期31卷 2023-2033页

作者： Hongliang LI Dong LI Yunhua LI School of Automation Science and Electrical Engineering Beihang University Beijing Aeronautical Science and Technology Research Institute of COMAC School of Aeronautic Science and Engineering Beihang University

This paper deals with the multi-index assessment method for evaluating coverage effectiveness of remote sensing satellite. Because a series of satellite activities such as imaging, moving target observation, and environment investigation need to know the coverage characteristics, the coverage capability of the remote sensing satellite is the most important index. Thus, it is very important to establish the method of effectiveness evaluation of coverage characteristics. This paper focuses on the assessment of coverage effectiveness of remote sensing satellite, and proposes and designs a multi-index evaluation method based on index weight using entropy weight method and analytic hierarchy process. With a simulation case, the effectiveness evaluation results of single satellite coverage and multi-satellite coverage performance are given for the proposed *** experimental results show that the established coverage characteristic model and the proposed assessment method are effective and right.

The effectiveness and reconfiguration analysis of Leo large-scale remote sensing satellite constellation is of great significance to satellite constellation system design and system *** 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.
