Abstract
GNSS(Global navigation Satellite system) is the system which determines the users' position using the navigation satellites. The position determination using GNSS has to be always Possible to appling GNSS to railway system widely. Especially, to apply GNSS to the safety-critical application, such as train control system, the satellite's visibility has to be always secured. This study describes the necessity of visibility analysis and the method. And also the visibility analysis of the stand-alone GNSS and the integration GNSS are performed and the applicability of GNSS for train control application is analysed.
