Since 2017, Rénag has been archiving GNSS data from the Orpheon network. Today, it is changing the way it distributes this data, which was previously restricted.

While these were initially restricted to scientific users on request, Orpheon network data operated by Rénag’s private partner Geodata Diffusion are now accessible in Rinex format, with a one-year embargo. This means they can be downloaded directly from the Rénag distribution server hosted at the Observatoire de la Côte d’Azur.

This means that a large part of the GPS and Glonass data archive recorded by over 200 stations is now available to all, without restriction, for non-commercial applications. Since March 2024, data have been archived in Rinex3 format, with new observations provided by the Beidou and Galileo constellations.

To use the most recent data (less than a year old) and distribute the associated results, each scientific user must sign the access request form appended to the data availability agreement. This agreement was renewed between Geodata iffusion and the CNRS in the summer of 2023.

These advances now enable the Rénag data center to prepare for the modernized distribution of Orpheon station metadata.
