Research on Comprehensive Evaluation Index System of Spatial Information Network Based on High-orbit Satellites

Abstract

Abstract. In this paper, for acquiring the initial set of indicators, the space-ground network and communication systems are researched deeply in the context of spatial information network. On the basis of the fundamental principle of index construction, by extending the classical comprehensive effectiveness evaluation criterion, the five criteria (coverage, timeliness, capability, accuracy and dependability) for spatial network test evaluation are proposed. After the mapping of the index and the criterion is completed, the index system is further decomposed and optimized. Finally, then a comprehensive evaluation index system of spatial information network based on high-orbit satellite system is proposed. The system has a certain significance and evaluation of the application value.
