EPOS TCS 10 2022 GNSS

EPOS GNSS TCS 2022 outlines the role of the GNSS Thematic Core Service (TCS) within the European Plate Observing System (EPOS). The document describes how GNSS data—transmitted from satellite constellations—supports geodetic research, including Earth’s shape, orientation, and gravity field. The GNSS TCS provides access to European and regional geodetic data, metadata, products, and software, fostering multidisciplinary research on Earth’s surface motion, from seismic activity to tectonic shifts.

The TCS coordinates data archiving, promotes best practices for GNSS station operations, and maintains open-source tools. It collaborates with EUREF and regional networks to ensure high-quality data and services, integrating them with EPOS to address societal challenges like geo-hazards and environmental changes. The infrastructure supports long-term access to solid Earth science data, enabling pan-European and global research collaborations.
