A New Approach for the Quality Control of Integrated Navigation Systems

Yang Gao

Abstract:	With the increased sophistication of integrated navigation systems, quality control becomes more important in order to detect system failures or misspecifications in the system, and to assure the accuracy and reliability of navigation. A current method based on the statistical testing of an innovation sequence is overviewed. The method, however, is shown to have difficulty in specifying the alternative hypotheses for testing and to isolate the sources of the failures. The results thus may be falsified. As a consequence, a new approach has been proposed in this paper, in which the test statistic used is stabilized through robust estimation. The method is capable of not only detecting failures in the system but also isolating their sources of the failures. A simulated example is given to test the performance of the new method and the results obtained are encouraging. Further studies are also identified.
