Active GNSS Station Data

The active GNSS network for Ireland is the result of collaboration between Ordnance Survey Ireland (OSi) and the Ordnance Survey of Northern Ireland (OSNI).

Search and download hourly RINEX GNSS files from any one of the permanent (active) GNSS network stations, enabling users to combine this industry standard format GNSS data with their own data for GNSS post-processing applications.

You can also check the health of any one of the active GNSS stations for the previous thirty days or to check the health of all the stations on a particular day within the last thirty days.

The station health matrices refer to whether RINEX data is available from a station for any given.
