The mission center interfaces with GNSS stations by retrieving raw files or RINEX files (typically every 15 minutes or hours) and converting them into consumable files (according to customer demand and IGS standards). It will also make available consumable data based on validation criteria from quality files. The data produced are available on the SEF (File Exchange Server) during 30 days.

All these DT data must be made available to partners in the scientific community, for internal CNES clients (Navigation projects including NTMF platform) and for external clients such as IGN (CNES partner for REGINA project and IGS Data Center), IGS and EUREF. The diagram below describes the diffusion of DT files from REGINA mission center. IGN REGINA stations are managed by IGN and data are also available on IGS data centers.
