Performance of Fault Detection and Exclusion for GNSS/Locata Integrated Navigation

L. Yang

Abstract:	To meet the navigational accuracy, integrity, continuity and availability required for many applications, Locata technology can provide an alternative to satellite-based navigation in difficult GNSS signal environment. This paper demonstrates performance-improvement, using GPS/Locata integrated measurements, upon application of the parity-space RAIM concepts. Fault detection and exclusion algorithm performance is validated through analysis of aspects of the computation of the Dilution of Precision (DOP), the Horizontal Protection Level (HPL) and the correlation coefficient between two failure modes that can indicate the quality of fault identification. The experimental analysis shows that if the Locata transmitters are developed in good configuration, the accuracy and reliability of the navigation system can be significantly enhanced.
