Enabling certification of satellite based localization in railways by combination of redundant sensors and map matching

Abstract

Satellite based localization systems are currently applied in various domains in transportation for information purposes. For example in railways for passenger information, in automotive for navigation or in aviation to precisely follow flight paths. These applications are mainly non-safety relevant because of a missing certification. In this paper a development strategy towards the certification of safety relevant applications in transportation with the example of railways is shown. For the certification of an application for transportation, several steps of a domain specific process based on the normative background to be analyzed have to be followed. Though this paper focuses on railways, the basic certification process in other domains is similar.
