英文摘要	In single constellation, such as GPS, BDS, Galileo or GLONASS, the tracked signals are susceptible under the obstruction with many high buildings or city canyon around. In this case, faulty satellite is just able to be detected by conventional Receiver Autonomous Integrity Monitoring (RAIM), while we cannot identify it with only one redundancy satellite. In this paper, we propose a novel RAIM scheme for False Detection and Exclusion (FDE) under 5 satellites by Receiver Clock Auxiliary (RCA), which ensures reliability and robust navigation of standalone Global Navigation Satellite System (GNSS) receiver. From the point of non-linear cases, Radial Basis Function Neural Network (RBFNN) is utilized to predict local receiver clock bias under current epochs, which provides one equivalent redundancy and fully implemented by non-linear transfer layer and linear combine layer. We creatively make full use of effective RBFNN algorithm to bring RAIM into force under low available satellites. Theoretical analysis and simulation results indicate that the proposed scheme yields a significant enhancement in single constellation.; EI; CPCI-S(ISTP); fcmeng@pku.edu.cn; 543-547
