Approach for Fault Detection and Isolation in INS/GNSS Tightly-coupled System Based on Chi-square Test
摘要
Abstract
An approach for fault detection and isolation of INS/GPS tightly-coupled system was studied,which could recognize single navigation satellite error automatically by the utilization of fault detection function,could eliminate the fault satellite and reconstruct measurements array,and could avoid the influence of the fault on system. The digital simulation environment was constructed,then simulations of method for fault detection and isolation were conducted,results of which indicated that the proposed method could detect and isolate the fault satellite in time,and could reconstruct measurements information,which ensured the accuracy and integrity of tightly-coupled system.关键词
