Multilayer comprehensive evaluation method of the receiver autonomous integrity monitoring based on entropy weight

Receiver autonomous integrity monitoring is the detection and identification for fault satellite by using of receiver redundant observations, this article presents a set of evaluation index system for receiver autonomous integrity monitoring, using based on information entropy method and AHP method calculates secondary index weights, and combining the two method, according to the combined weights determinate first-level index by the information entropy method. Finally using fuzzy comprehensive evaluation method finds the final evaluation results. This approach can have a good assessment for the receiver autonomous integrity monitoring performance after validating.
