| Abstract: | The fault detection and identification methods of Snapshot and Filtering are applied to detect and identify the single and multiple faults GNSS observations.Compared the performances of false alarm rate,miss detection rate,correct identification rate,computation consuming time,availability and precision between Snapshot and Filtering methods,the Filtering FDI method performs,especially in multiple faults identification,is better than Snapshot method. |
