Integrating GNSS Data Across Europe: Advancing Geodetic Research and Applications

The European Plate Observing System (EPOS) facilitates access to GNSS data and derived products through its GNSS Thematic Core Service (TCS), harmonizing data availability from European networks. Rigorous quality control of RINEX files with GNSS measurements ensures the integrity of the raw data, ensuring reliability for subsequent processing and analysis. By implementing FAIR (Findable, Accessible, Interoperable, Reusable) principles, EPOS-GNSS enhances accessibility and supports advanced geodetic research and Earth system monitoring.

A central feature of EPOS-GNSS is GLASS, which supports the dissemination of GNSS data and derived products, including time-series, velocity fields, and strain rate maps. GLASS facilitates seamless access to these resources, utilizing international standards for data compatibility and interoperability. Although the data and products are distributed across different nodes and repositories, GLASS ensures a unified interface for users through the dedicated EPOS-GNSS portals or the EPOS Platform.

We will present the latest developments in the implementation and operation of EPOS-GNSS services, which are contributing for the scientific community to address key scientific and societal challenges, such as monitoring Solid Earth processes, while also supporting other scientific and technical applications. By streamlining access to comprehensive GNSS datasets and derived products, EPOS-GNSS enhances research capacity and fosters innovation in geodetic studies across Europe.
