Summary

The European Commission (DG ENTR) has recently required support for the Standardisation of Satellite Navigation Systems (GNSS) for Terrestrial applications. Matching those needs, a consortium led by FDC (France) has launched the SAGITER project. Starting in February 2013, SAGITER will last two years and aims at compiling all the technical notes produced during the project timeframe to be submitted for its approval to the ETSI TC-SES/SCN Group. In this project, a unified expression of needs from the different user communities (rail, road, etc.) is being sought, concerning common requirements on GNSS applications. SAGITER targets at ensuring consistency with the current on-going space industry standardisation activities in the European Telecommunication Standards Institute (ETSI), the European Committee for Standardisation (CEN), the European Committee for Electrotechnical Standardisation (CENELEC) and the Union Industry of Signalling (UNISIG). The project will finalize the standardisation process for EGNOS and Galileo in key application areas, and specifically for the terrestrial transport and multimodal domains and will liaise with other standardisation bodies (ISO, OMA, 3GPP, UNISIG GNSS WG). This paper focuses on the application of this unified approach for standardisation to the railway field: it reports on the activities performed regarding the definition of reference architectures for standardisation of locator units based on GNSS and will analyse the resulting benefits for rail stakeholders. The reference architecture diagram for the railway location unit case includes as basic technical enablers: a GNSS sensor; inertial sensor; hybridization and integrity algorithms; and communication modem. In addition, significant activity has been carried out on the definition of the operational environments, considering the elevation mask, signal attenuation, multipath, interference and user dynamics.
