The GNSS Data Gateway is the central point of access of an e-infrastructure that is designed to store and disseminate validated GNSS data and metadata provided by existing Research Infrastructures. The e-infrastructure is based on a top of an unique node, hosted at the GNSS Data Gateway, that centralizes validated file metadata from independent local nodes and validated station metadata from the station metadata submission center (M3G). On the GNSS Data Gateway, users can search and download for available EPOS GNSS data and metadata from all over Europe, including some EUREF Permanent GNSS Network (EPN) ones. Data and metadata are distributed to the public through a web interface and command line clients using a dedicate API.
