英文摘要：

This paper presents a fast method based on classical probability and the Laiyite to discriminate GPS abnormal data,which is simulated in VC＋＋ and Matlab. Experimental results show that the method has the advantages of rapid handling speed and high efficiency,discriminating and eliminating GPS abnormal data efficiently. Finally, the method is applied to deal with the abnormal points of positioning - data for aids of navigation. Instances of spot application verify the feasibility and high-efficiency of the method,which enhances the ability of anti - interference of GPS abnormal data for Pharos RTU.
