A new European service to share GNSS Data and Products

This paper describes the new GNSS data and product services that have been developed within context of EPOS (European Plate Observing System) European Research Infrastructure Consortium (ERIC), which is part Strategy Forum on Infrastructures. These services, optimized for Solid Earth research applications, endeavour to harmonise, standardise Global Navigation Satellite System (GNSS) collection processing. They implemented by members Data & Products (EPOS-GNSS), one Thematic Core Services (TCS) with active support national pan-European infrastructures (in particular Regional Reference Frame Sub-Commission Europe (EUREF) International Association Geodesy). The use from dozens diverse networks, installed not specifically geodynamic studies, created additional requirements an organizational technical point view, solutions we describe in this article. flows suppliers analysis centers various TCS Product Portals are described, as well their integration into overall system. made through GLASS (GNSS Linkage Advanced Software System), a dedicated software package since 2016, whose architecture functionalities detailed here. Time series other products computed at several described quality control steps performed. Finally, user cases presented demonstrate how different stakeholders (from providers scientists) can benefit efforts being carried out EPOS- community.
