|Abstract:||This paper describes an integrity monitoring method that can be applicable to GNSS-based train localization. Integrity monitoring of GNSS measurement results is required in order to apply GNSS to the train control systems. We have proposed the integrity monitoring method based on the precise receiver clock  . In this paper, we introduced the integrity monitoring method on the two dimensional surface. We evaluated the method by using the GPS signal generator. In the scenario, the receiver receives non-line-of-sight (NLOS) signals. We showed the calculated protection level always contains the true position. Moreover, the size of the protection level along the track when the receiver receives only lineof-sight (LOS) signals is reasonable enough to operate train control systems. This result suggests that our integrity monitoring method is effective for the train control systems.|
