The EPN provides 1Hz RINEX files in 15 min intervals, which are either coming directly from a station or are converted from a real-time observation stream coming in RTCM v3.x stream format. Which stream and which stream conversion tool have been used is described in the RINEX header. The files are stored as RINEX v3 with long filenames, containing Multi-GNSS data.

1. For EPN stations which are included in the IGS network: The 1Hz RINEX files are currently made available from the IGS Regional Data Centre BKG.
2. For EPN stations that are not included in the IGS network: The 1Hz RINEX files are currently made available from the EPN Regional Data Centre BKG.

The 15 min files are separately stored in hourly sub-directories for a period of six months. Afterwards, they are merged in one tar file on a daily basis, replacing the hourly sub-directories.
