AI Technical Summary

Technical Problem

Existing satellite constellation fault assessment methods typically use only a single indicator, resulting in low accuracy of assessment results.

Method used

A multi-dimensional performance index fusion method is adopted, which integrates three types of indicators: task realization performance, resource utilization rate and timeliness. Combined with the entropy weighting method and the analytic hierarchy process, the comprehensive performance evaluation value of the satellite constellation is calculated.

Benefits of technology

It enables multi-faceted evaluation of satellite constellations, improves the accuracy and precision of fault assessment, eliminates differences in the order of magnitude and unit dimensions of evaluation indicators, and integrates objective information and subjective decisions into the weights.

Abstract

The application discloses a constellation health state diagnosis method based on multi-dimension performance index fusion, and has the characteristics that the steps are as follows: (1) based on the task implementation performance, resource occupation rate and timeliness of a satellite constellation when performing a task, the satellite constellation index and the satellite index of each satellite in the satellite constellation are calculated; (2) each constellation index and each satellite index are standardized to obtain the standardized constellation index corresponding to each constellation index and the standardized satellite index corresponding to each satellite index; (3) the standardized satellite indexes of the same category of all satellites are respectively grouped into a set of standardized satellite index sets; (4) based on the entropy weight method and the analytic hierarchy process, the fusion weight corresponding to each standardized constellation index and the standardized satellite index set is obtained; (5) based on the fusion weight of each standardized constellation index and the standardized satellite index set, the comprehensive performance evaluation value of the satellite constellation is obtained, and then whether the satellite constellation has a fault is evaluated.
