Vadim A. Rumyantsev, Vyacheslav P. Shkodyrev

Abstract

A failure diagnosis scheme using the chi-square Shewhart chart and the ART neural network is presented for navigation systems. After a failure is detected ART neural network is applied to determine when the failure happens, how serious the failure is and where the failure is located. The application of the proposed scheme to the problem of the Global Positioning System (GPS) integrity monitoring is discussed.
