GDC Archive Access

Access to the GDC archive data is provided by HTTPS and currently anonymous FTP. As the FTP protocol has many security weaknesses we encourage you to use the HTTPS protocol for downloading files. Support for FTP will be turned off in the not so long term.
There are many tools available that support these protocols, e.g. You can further search and download files using our Filebrowser, Fileserver or the RINEX Search.

Our REST API is still under development and not suitable for external usage yet.
